First, let's figure out what kind of connection this is. SSL is a cryptographic protocol that makes the connection between the browser and the resource you need more secure. Sites that use this protocol are signed as https://. You can absolutely stop worrying about information leaks if the certificate was completed in the required form and has not expired.

Methods to solve SSL connection error?

Method No. 1 Check the time and date settings

In your browser you may receive the message “ The server certificate is not yet valid.”, which means that the time for the certificate to work has not yet come. In this case, the problem is likely to come from you rather than from the site.

All you need to do is check the date and time on your PC. These settings are most often lost due to a dead battery on your motherboard. Just set the required time and the SSL connection error will disappear.

Method No. 2 Checking the Firewall and Antivirus settings

Sometimes the resource you go to decides that your security utilities are spyware and blocks them. To check for this problem, simply disable the check https:// in the antivirus.

Let's look at the example of an antivirus Avast how to do it go this way: Settings -> Active Protection -> Web Shield Settings

Inside this tab there is an option “ Enable HTTPS scanning” which you need to uncheck.

Method No. 3 Update the browser and system

We know that the advice to update is a rather hackneyed topic, but still it’s time helpful advice. Update your browser and entire system. Perhaps this will solve your connection problem SLL.

Method No. 4 Malicious utilities and viruses

IN modern world Such things have incredibly huge functionality. Let's look at some of the skills of these “pests”:

• Can bypass anti-virus protection.
• Makes your PC invisible on the network to other PCs.
• They block various sites.
• They may just show you a whole bunch of ads.
• They change your start page, without your knowledge.
• Blocks port 80, etc.

Scan your PC using special utility Anti-Malware Bytes. It will help you find various threats to your system. Even if you think you're keeping your PC squeaky clean, rest assured there's something there.

In each situation, the cause of the SSL Connection Error is individual. It can be caused either by the server from which information about the site is requested, or by the user’s computer. If the source of the problem is the site visitor’s computer, the solution should be sought in the browser from which the resource is accessed.

SSL Connection Error is typical mistake for browsers based on the Chromium platform. Such browsers include not only Google Chrome, but also its various analogues: Yandex.Browser, modern versions of Opera, Comoda Dragon and others. In all of them, the error is caused by a problem with the client authentication certificate.

If an SSL connection error occurs, the browser will not be able to access one or more sites due to the message SSL Connection Error appearing in the window. To continue using the Internet to its fullest extent, you need to get rid of the problem. Below we discuss what to do if an SSL connection error appears in Google Chrome, but the instructions are universal and the problem is fixed in a similar way in other browsers:

1. Please update your browser. If you encounter any problems related to connecting to sites on the Internet or playing content on them, you should first install the latest version of your browser. Most often, the Google Chrome browser updates automatically or prompts the user to download latest version, but many ignore the recommendations, which leads to various problems.

To update Chrome browser, you need to go to the settings and click on the “About” item. Next, you need to pay attention to whether the latest version is installed. If not, your browser will need to be updated.

1. Examine installed extensions. Often problems with browser performance arise due to various extensions. Inexperienced users may accidentally install virus extensions that harm the computer. Also, some licensed extensions may conflict with certain sites or scripts running on them, which will result in an SSL connection error.

To check if the error is related to extensions, go to the Google Chrome settings and then switch to the “Extensions” item. Disable all running extensions and try again to connect to the site on which the error appeared. SSL message Connection Error. If the error is not corrected, proceed to the next step.

1. Reset your proxy settings. To connect to sites on the Internet, Google Chrome uses proxy server settings. They can go wrong for various reasons: due to the actions of a third-party extension, a virus, one of installed programs on the computer and so on.

Resetting the proxy server settings to default values ​​is quite simple. Just go to the Google Chrome settings, select “Show advanced settings” and in the “Network” column click on the “Change proxy server settings” button. Next, you just have to select the option with automatic detection of parameters and you can try to launch the site on which the SSL Connection Error appeared.

1. Make sure the problem is not related to your antivirus. Antivirus applications do not work perfectly, and because of them, various problems may arise when connecting to sites on the Internet. To check whether the antivirus is related to the SSL Connection Error, you need to disable the anti-malware program and try to access the site.

Important: Disable your antivirus only if you are sure that the site you are visiting does not contain viruses.

If disabling your antivirus helped fix the SSL error, you will need to find an item in its settings that allows you to create an exception for the SSL protocol.

When none of the above tips help get rid of the problem, you should make sure that the site is currently accessible. It is possible that the error occurs on the server side, and it is not possible to access the resource from all devices.

Client Authentication Certificate. What does authentication mean? Causes of SSL Errors

Here's a typical question:

Error 107 appears when accessing https://vk.com/. When I try to log in, a message appears: “Cannot authenticate via a secure connection. Most often this happens when the current date and time are set incorrectly on your computer. Please check your system date and time settings and restart your browser."

Date and time are correct. Hosts file also normal. There are no viruses. Reinstalling Chrome didn't help.

Here we suggest how to fix an SSL error connecting a connection to vk.com or other sites. For example, a secure connection to the server cannot be created. There could be a problem on the server, or a client authentication certificate is needed, which you do not have and is issued:

Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.

Such ssl errors VK or error ssl yandex, google problems may occur frequently if you do not solve some problems. Here are some guidelines to resolve the SSL error. So, if you encounter an SSL error, try these steps:

• Check if the date and time on your computer are set correctly.
• In your antivirus settings, try temporarily disabling HTTPS protocol checking
• If the problem occurs on Windows XP SP2, update it to SP3.

SSL protocol error This often happens with the Eset Smart Security 5 antivirus, which incorrectly filters the https protocol. You need to disable https check and everything should work.

If everything is fine with SSL on the site, then most likely the problem is that Kaspersky intercepts SSL connections and then proxies them to the browser using its own crooked certificate. A normal browser will display an error warning about a MITM attack. You should try disabling SSL connection checking.

Often, if there is an SSL error, everyone refuses to work installed browsers. The only way out is to use standard IE, which in 90% of cases does not produce such an error. This browser can be used until a solution to the problem is found. In simple words An SSL error indicates that a connection to the server cannot be established for some reason.

As noted above, you need to check the settings of your antivirus, since it can block connections, which is why all the problems arise. You may need to add your browser to exceptions and set less stringent controls on incoming and outgoing traffic.

• Check your firewall settings. If necessary, lower the protection level.
• Also in Google error SSL connections can occur when you do not have an antivirus program and the system is infected. In principle, this can be solved either by reinstalling the OS or by scanning the system for infected files.
• The time settings are lost. Consequently, a discrepancy is detected on the server, and the connection is determined to be unreliable or insecure.
• An outdated browser is also a cause of SSL errors.

2. This is necessary to know, for example, to organize an xml search on Yandex. It indicates the IP address of your server from which search requests are coming.

Public key protocols allow you to establish authorized encrypted communications between nodes in internal networks and on the Internet. There are three models of authentication carried out in these protocols; they are used both individually and in combination.

• Client authentication. Allows Windows server 2000 VPN or IIS Web server to authenticate the user using standard public key encryption methods. Verifies the authenticity of the client certificate and public ID, and verifies that this data was generated by a certificate authority whose root certificate is installed in the list of trusted CAs. This verification is very important if the server is a bank that transmits confidential financial information to the client and needs to confirm the identity of the recipient. Figure 8.1 shows the authentication process.
• Server authentication. Allows the VPN client or SSL/TLS client browser to verify the server's identity by verifying that the server's certificate and ID are correct and that the certificates were issued by a certificate authority (CA) whose root certificate is present in the client's list of trusted CAs. This confirmation is important for a website user who is submitting a credit card number over the Internet and wants to ensure that it is the correct server.
• Mutual authentication. Allows the client and server to authorize each other at the same time. Mutual authentication requires that the client and server have digital certificates and corresponding root CA certificates in their trusted CA lists.

Most commercial CAs, such as Verisign, are built into Netscape and Microsoft browsers as default root certificates. Users and network managers do not need to install certificates; server authentication works automatically. If the organization acts as its own certificate authority, then it is necessary to additionally install the root certificate on all browsers of intranet client computers and provide appropriate instructions.

Figure 8.1 shows how SSL/TLS authentication works. In practice, most websites only use server-side authentication using a digital certificate, since distributing client certificates to all site visitors is a huge undertaking (somewhat easier if clients are connected to an intranet).

An argument against using certificates on client computers is that it opens the system to potential dictionary attacks. The browser client authenticates the server using public key methods, but the server simply uses passwords to authenticate its clients, so a hacker can perform a password guessing attack. The management of companies that do not use certificates believes that the cost of development is higher than the real threat; Like most business decisions, this statement is based on economic factors.

Almost every user has encountered many problems in the browser. One of these problems is SSL connections, which prevents you from viewing the pages you need. Let's look at all the ways to fix this problem.

A few more simple ways to solve the problem

If you don’t have time to deal with browser settings or scan the system, then you can try several times in a row which you need to log into. It is likely that after this the information will be partially displayed. However, in the future you will need to do everything according to the instructions. Another way out is to reset your browser settings to Default, that is, to standard ones. This will enable/disable all necessary plugins and scripts. It is also recommended to clear the cache, which sometimes gives a positive result. You can also go to Windows folder, then system 32, then in drivers to find the “etc” file there. The last line should look like this: 127.0.0.1. Everything below this inscription must be removed. After this, Google's SSL connection error will disappear.

Please note that sometimes sites without reliable or expired certificates are a kind of virus carrier. In this case, it is normal to see a window that says “SSL connection error.”

What to do if you still need to visit the resource, you ask. To do this, you must continue the connection by confirming your decision. In this case, you may get a virus on your computer, which is not good. Although if you have it installed, it will give you a corresponding message and automatically block you from working with the malicious site.

Now you know what an SSL connection error is. We also figured out how to fix it. I need to say a few more words about the fact that you need to periodically clear Cookies in your browser. This will not only speed up page loading, but will also relieve you of the problem described above. It is advisable to at least occasionally conduct a full system scan for viruses and suspicious files.

You must understand that if you get this kind of error, then something is wrong with your computer. First of all, check the time. If the year, month or time of day is not correct, you need to correct it. To do this, in your desktop tray operating system Click on the clock several times and set the real values. This usually solves the problem immediately. If this does not happen, go to and see if SSL protocol support is enabled. If everything is as it should be, then most likely the problem is in the antivirus program or malicious file which blocks the connection. Removing or moving to quarantine should help.

Authentication is a procedure for verifying the identity of an object or subject.

1. We can talk about verifying the user's authenticity by comparing the password he entered with the cipher stored in the database.
2. Authentication is also called checking the checksum of a file for compliance with the amount that was declared by the author of the file.

Client Authentication Certificate

Client certificates are intended for owner authentication when it comes to secure client-server applications, or for use in electronic document management systems during the creation and verification of an electronic digital signature (EDS).

Strict control of the reliability of the information in the certificate allows us to ensure the strictest cryptographic authentication, which makes it possible to confirm the signature of the certificate owner under electronic documents.

The production and maintenance of client certificates is carried out on a paid basis.

Other materials in the series:

• Authenticating Clients to Online Services Using Digital Certificates - Summary

In the first part of a series of posts about client authentication using certificates, we did a throw-in and talked about the main points of this topic. We realized that certificates are much more secure than your passwords (if you prepare them correctly!). In this part I propose to engage in theory. Long, difficult, tedious, but necessary. Today's theory will consist of studying the general principle of how certificate authentication works and how it looks in communication between client and server.

General certificate authentication scheme

When a user authenticates with a certificate on a website, the process goes something like this:

1. A user requests access to some network service;
2. Upon request, the server sends its server certificate (SSL certificate) to the client. The client checks it for validity. If the check fails, that's the end of it;
3. If the check is successful, the client requests access to the service resources;
4. The service is configured to require user authentication and sends the available (on the server) authentication methods to the client. In our case, this is a requirement for a client certificate;
5. The client sends to the server the public part of its certificate and a certain amount of data signed with the client certificate. The server checks the client certificate for validity. If the certificate does not pass verification, the conversation between the client and server ends. If the certificate passes verification, the server attempts to match (or associate) the certificate with account user. If the matching fails, the conversation ends.
6. If the account is found and the certificate can be associated with it, the server begins establishing a secure channel. After establishing this channel, the server provides the user with resources to the extent that access lists (ACLs, for example) allow it.

I found it necessary to expand on the last point a little so that you understand the general structure of this channel (since people have some misconceptions about this):

1. The client requests the establishment of a secure channel;
2. The server agrees and sends the client a list of supported symmetric encryption protocols;
3. The client sends its list of symmetric encryption protocols to the server;
4. The client and server negotiate and select the most suitable protocol. For example, - I can do DES and 3DES, but what can you do? - And I only know 3DES and AES. - Great, let's use 3DES then;
5. The client, on its side, generates a session symmetric encryption key and encrypts it with the public key of the server certificate. This process is called Key exchange. As we know, only the web server can read this key, because only he owns the private key that is associated with a specific SSL certificate;
6. After this, all transmitted data is encrypted with this particular session key. Remember that when transferring data, certificates are no longer used (and many people believe that all data is encrypted with public keys of certificates). Certificates are used only when updating the session key (which changes periodically).

A slightly different process occurs during an interactive login or login to a terminal server via Remote Desktop using a smart card.

Logon with a smart card or PKINIT

Interactive authentication in Active Directory using a certificate is not an independent mechanism. As always, the main authentication protocol in the domain is Kerberos. To ensure interaction between smart card authentication and Kerberos, a simple PKINIT protocol is used. PKINIT, in turn, is just an add-on to Kerberos (or a protocol extension). Here's roughly how it works:

Note: If the user already has a corresponding service ticket (TGS), only steps 5 and 6 are performed.

1. The user enters the smart card PIN and sends an AS-REQ request to the domain controller (aka Key Distribution Center - KDC). This request contains the pre-authentication data PA_PK_AS_REQ, which in turn contains the login certificate and signed timestamp and optional attributes. As optional attributes, the client sends a list of supported algorithms, root CAs, Diffie-Hellman parameters, etc. A more detailed request structure (and there are quite interesting things there) can be found in RFC 4556 §3.2.1 (clause 5 on page 12). In this regard (for example, transferring a list of trusted root CAs from the client to the server), the time of logging in with a smart card will be much slower than with a login/password combination. Plus the costs of cryptographic operations.
2. The KDC server verifies the request and tries to associate the received certificate with the user account. If the matching of the certificate to the account is successful, the KDC generates an AS-REP response, including a Ticket-Granting Ticket (TGT) and other necessary information. The response is signed with the certificate of the KDC itself (which is why, when using a smart card for login, the KDC server must have its own certificate (we will talk about it in the following articles).
3. The client validates this response and verifies the signature (along with the KDC certificate). If everything is fine with the response and certificate, the client, based on the existing TGT, generates a Ticket Granting Service request - TGS-REQ for access to a specific service and sends it to the KDC.
4. The KDC checks the TGS-REQ request and, if the verdict is positive, generates a Ticket-Granting Service (TGS-REP) response, including all the necessary information for an interactive login, including all the necessary SIDs and credentials for authentication using NTLM.
5. The client generates a special GSS-API token (

Ssl error how to fix:

1. Check the time and date.

As you can see, in the second case there is the text “The server certificate is not yet valid.” those. The certificate's start date has not yet arrived. This is unlikely to be a site problem. Most likely the problem is on our side.

In this case, everything is corrected simply. Let's check the time on our computer (tablet). Not true.

On motherboard The computer's battery ran out, which led to the time being reset back to 2002. Having set the time, we see that the SSL protocol error has disappeared and the site opened safely.

2. Check your antivirus and firewall settings.

The SSL error associated with an incorrect date is the most common. But what if the date is okay? What else could cause the error?

Most antiviruses and firewalls check the ssl protocol and it often happens that the server with which you are exchanging data mistakes your antivirus for a spy - an attacker who is trying to intercept your data. You can disable the https:// check function and check whether the error appears again.

Let's look at disabling https checking using the example of one of the most popular free antiviruses- Avast.

Open the antivirus management window, select “Settings”, then “Active protection”. Click on the button<Настройки>Web screen. A third window will open in which you need to uncheck “Enable HTTPS scanning”.

Within the scope of this article, we will not be able to consider all popular antiviruses and firewalls. Yes, there is no need. In other antiviruses the logic is approximately the same. So we hope you can figure it out for yourself.

3. Browser and system update.

The time is set correctly, HTTPS checking is disabled in the antivirus, and the SSL error haunts me. The advice is pretty standard, but nonetheless effective. Update your browser, update your operating system.

I remember in 2012, the Google Chrome browser was updated to version 18.0.1025.151. For everyone who had Windows 7 - x64 installed at that moment, it made it impossible to connect via ssl. Everything was fixed with the next update.

It happens that an update simply “corrects” some shortcomings, replacing outdated information (settings) with new information.

Be that as it may, it won't hurt to update.

4. Malware, viruses and other “evil spirits”.

Lately, there have been so many computer “evil spirits” that there is simply no way to keep track of what they can do and what they can’t do. Malware is especially famous for this - a type of malware that can:

1. Bypass antivirus protection.
2. Make the computer “invisible” to other computers on the network.
3. Block access to sites, such as Kaspersky and Doctor Web.
4. Attract advertising to all browsers.
5. Replace without asking start pages browsers.
6. Download even more Malware.
7. Block connections on port 80, as well as block ssl

… and many many others. How much imagination is enough?

So, download CureIT and Anti-Malware Bytes, update your antivirus, turn off its screens for a while so as not to interfere. And start scanning. In 90% of cases, on a seemingly “clean” computer, these two programs find something.

As you know, any application or program can fail one day - nothing is perfect in the world. So in the Google Chrome browser you can expect an SSL connection error. What does it mean and how to deal with it?

An SSL connection error occurs when opening a website, and such a website can be any resource, including both popular and not so popular ones. The error literally means the following: “Unable to connect to the server. The problem could be due to a server or client authentication certificate that you don't have."

This is what the error looks like in the browser:

Please note that it can occur not only in, but also in a number of other browsers that are based on Chromium: New Opera, Comodo Dragon, etc.

Problem and solution

I would like to immediately note that the reasons why this error in the browser may not be related to each other. Therefore, the solution for each case will be individual. So I'll talk about a few possible solutions.

• The first step is to update your browser. Yes, the same Chrome is automatically updated, but in some cases the update can be disabled by the user. In addition, a glitch in the application itself cannot be ruled out. Therefore, click on the settings button, select “Help/About browser” and see if the current version browser.

• Let's move on. Pay attention to the antivirus system. The fact is that it can block the SSL protocol as potentially dangerous, so it simply blocks it. In this case, you can try disabling the antivirus screens for a while and check whether the site opens in this case. In addition, in the settings of the antivirus program itself, you need to create an exception for this type of protocol.

• If used Windows version XP SP2, it must be updated to SP3. This solution was found on one of the forums and, according to user responses, it turned out to be very effective.

• Theoretically, the problem could be hidden in installed plugins in the browser itself. Go to settings, select “Extensions” and disable all extensions available there. If after this you were able to access the site, then the problem is in the extension and you just have to find which one is blocking the connection (disable extensions one at a time and you will find the culprit).

• Check your proxy settings. Go to your browser settings, find the “Network” subsection and click on the “Change proxy server settings” button. If a proxy server is specified in the network settings, it is possible that this is the problem. Select "Automatic detection of parameters" and go to the site.

• Alternatively, the problem may be with the site itself. But until the site owner sorts it out, you are unlikely to be able to access the site itself.

You can tell us about your solutions to the problem using comments.

If the site has SSL installed, the page opens securely https protocol:

The green color in the address bar signals to users: personal data will not be stolen here (number bank card, mail account, password).

It’s annoying when a green traffic light turns red at the wrong time. It’s doubly annoying if, instead of a secure connection, you suddenly see on the website: SSL protocol error. Why this happened and how to fix and remove the SSL connection error, read below:

Check in advance

Make sure you don't confuse the SSL connection error with other problems. If your website stops opening in your browser, first check:

Is a redirect from http to https configured for /;

What domain is the SSL certificate installed on? An SSL certificate is registered for a specific domain. That is, if the certificate is installed on a domain and you accessed through the address shop., then an SSL error will be shown.

If you have a free SSL certificate installed, it only applies to the domain itself and the “www” subdomain: and www.. It does not work for other subdomains. If you need an SSL certificate on a subdomain, order a separate certificate for the subdomain:

If there are no problems with this, continue reading the article.

Why does the SSL error occur?

• The system clock or calendar settings have gone wrong;
• your antivirus program scans data transmitted via the HTTPS protocol and may block some traffic;
• the settings of the browser itself have changed;
• a malicious script is triggered.

SSL protocol error, what to do?

Below are 4 drop-down blocks. Each contains an answer to the question of how to correct the error depending on the cause.

System clock and calendar settings

If the time settings on the computer are lost, the browser will warn:

In Google Chrome

In Mozilla Firefox

The solution is simple: set the correct date. To prevent the error from recurring, enable synchronization with an Internet time server ( system settings Dates and times).

Antivirus program settings

If everything is fine with the clock and the SSL error is still there, check your antivirus program settings. Most likely it includes "check https protocol". Check if it is enabled, the program will not accept or the certificate is protected Let's Encrypt. Try disabling the function and visiting the site again.

If the SSL error persists, disable your antivirus program and open the site. Did this solve the problem? Changing the utility will help.

If this does not help, do not forget to enable your antivirus program and look for the solution below.

Browser settings

1. Open the site in another browser;
2. Check if you are using the latest version of your browser. If not, update it to the latest and open the site again;
3. This is probably a browser glitch. In this case, restart your browser and try to access the site again;
4. If the problem persists, disable web antivirus components in the Extensions.

A radical way is to reset the settings to the original ones. Use it as a last resort.

You can also change your browser to Internet Explorer until the problem is resolved. There is no SSL error in this browser.

Sometimes an SSL error indicates real threat: The browser protects you from online scammers. It is likely that your browser opens a clone site to which you are redirected.

If you suspect hostile interference, scan your computer with an antivirus program and remove any existing viruses.

If the problem remains after the listed options, contact a specialist who will diagnose the specific case and identify what the error means ssl connections and will fix it.

One day, when I turned on my computer, I tried to go to my favorite site that I regularly visit, and unexpectedly received an unpleasant “gift” from the browser in the form of a message: "Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.". Trying to figure out the reasons for the dysfunction, I started visiting other familiar sites, trying to track down which of them showed a similar message. Some sites basically did not want to load, giving the error ERR_SSL_PROTOCOL_ERROR, while I visited others without any problems and no SSL protocol errors occurred.

Trying to understand the reasons for the problem of loading sites, I had to study many sources, and now I will tell you what exactly needs to be done to correct this situation with the ERR_SSL_PROTOCOL_ERROR SSL protocol error, if you also encountered it. So, first things first.

As you know, SSL is a cryptographic protocol that ensures the security of Internet connections and until recently was widely used for exchanging instant messages: in e-mail, Internet faxes, IP telephony, etc. Now SSL has lost its status as a reliable and secure protocol, experts have discovered It has a number of vulnerabilities, and today the SSL protocol is increasingly being replaced by the more reliable TLS.

However, at this time, all major browsers still use the SSL protocol, so any user may encounter problems using it, in particular, with the mentioned error 107 (as well as similar 101 and 112), which occurs when the connection security is violated. This ERR_SSL_PROTOCOL_ERROR SSL error is especially common on Google Chrome, but it is also common on other browsers. To solve this problem you need to take a number of actions, which I will discuss below.

Perhaps it's a virus?

To begin with, it wouldn’t hurt to check your computer for viruses using special programs level Trojan Remover or Dr.Web CureIt. The reason your browser is not working correctly may be due to your computer being infected with various malware.

What happened to the date and time?

You may be surprised, but this very factor may be the cause of error 107. Check that the date and time in the computer settings are correct, and if necessary, change the date and time to the correct ones by right-clicking on the time bar at the bottom right of the screen.

1. Select "Date and Time Settings";
2. And then click on “Change date and time”, enter the correct data and confirm the changes.

Changing antivirus settings

Go to your antivirus settings and try disabling protocol checking for a while HTTPS. This is especially true for owners of the Eset Smart Security Nod32 5 antivirus; for many of them, the problem was solved in this way.

1. If you have Eset, then go to settings, there select “Internet and Email»;
2. Next, “Protection of Internet access”, select “HTTP, HTTPS” and check the box next to “Do not check the HTTPS protocol”;
3. Click “Ok” and confirm the action.

In addition, antiviruses such as Avast or Kaspersky can intercept SSL connections and use their own personal certificate, often far from perfect, when surfing the Internet. Try disabling SSL connection checking in the following antivirus programs.

In addition, you can try putting your browser in antivirus exceptions, at least temporarily. This may help resolve the SSL protocol error called ERR_SSL_PROTOCOL_ERROR.

Updating Windows XP

If you are a retrograde and a lover of antiquities, and are still using Windows XP with SP2, then update it to SP3, this may also help solve the problem. Make sure your SHA-256 algorithm is supported.

Is the browser or firewall to blame?

Try lowering your firewall and updating your browser if you've been using it for a while. Old version browser may be causing error 107.

Try CCleaner

According to some users, cleaning the system using CCleaner programs helped to effectively cope with this error in the browser. Try to take advantage of CCleaner's capabilities too.

Conclusion

This error 107 is one of the common problems when working with SSL connections. Avoid appearing on your computer malware, try to work only with new software, monitor the correct date and time, set your antivirus settings as recommended above - and you will avoid the “Error 107. SSL protocol error” warning appearing on your personal computer.
