Often, many Internet users, when working in the Opera online browser, are forced to solve a problem that results in a connection failure. Sometimes such a failure is detected as an SSL error. How to remove SSL error in Opera?
In the specified browser, it is easy to fix it if the user is aware of the source of its occurrence. Let's look at several probable causes of the error and ways to get rid of the problem.
Features of the error
If you analyze the initial causes of an error of this type, you first need to find out what exactly it is. Typically, such a failure is a message that is sent to the security system.
SSL technology is quite similar to HTTPS and is a system of secure Internet connection when the information that the user’s terminal sends and receives is encrypted. The SSL protocol uses a special list of certificates that are provided to online resources. They serve as confirmation of the security of a particular Internet site.
When you receive a notification that a certificate error occurred in the Opera browser while connecting to an online resource, you should not rush and go to the web resource. Often this may not be very safe. However, this is by no means an isolated situation in which such a failure can occur.
Virus infection
A common situation when an Opera SSL error occurs is simply when threats such as viruses, applets or harmful codes enter the system. They are capable of partially blocking the connection, and at the same time installing their redirection to other Internet resources, which are generally not safe. Therefore, it is immediately important to pay attention directly to the address line. Usually, instead of the request that was entered, a completely different address will be written there.
In this case, experts advise not to use the installed antivirus to find and eliminate the danger. It is advisable to use a specific portable utility or boot before starting the system from a disk like Kaspersky's Rescue Disk. By the way, the latter method is considered more preferable, since current viruses can settle in the RAM, in boot disk sectors, and at the same time in logical partitions.
Firewall and antivirus settings
Often an SSL connection error in Opera occurs due to an authentication problem in the browser. As a rule, its occurrence is caused by prohibitions that are stored in the settings, as well as the parameters of the Windows firewall and antivirus scanners. 
How to fix SSL error in Opera? There are two ways: add the required Internet resource to the list of exceptions of the antivirus program or do the same, but for an online browser, in the firewall settings. Although it is possible to completely disable the firewall, but only when a licensed version of the antivirus is installed on the terminal, which monitors the prevention of external threats directly online.
Inaccurate date and time
The presented error can also occur due to incorrectly set time and date, although this is considered an indirect cause. It is important to take into account that, in particular, the date was set for entire years in advance. When the certificate validity of an Internet resource has expired during this interval, the Internet browser defines it as expired. The same applies to setting the date, which is done whole years ago. Here the opposite situation is observed, in which the certificate has still become valid and is not recognized as real. 
It is possible to cope with this problem if you set the time and date correctly in the system parameters. However, sometimes this may not work, so you will need to address the system time and date parameters located in the BIOS.
Modifying SSL settings in the Internet browser
Another reason for the error occurs when the main browser settings are incorrectly configured, namely, support for the SSL protocol.
In this case, you will need to go to the main browser menu. After this, you need to go to the advanced settings one by one and open the tab responsible for security. This menu has a special button to enter the section where security certificates are located. In the window that appears, you need to select the “SSL” inscription. After completing this procedure, the changes must be confirmed by clicking on “OK”, after which the browser will restart. 
As for the cases when a plugin error occurs in Opera (it doesn’t matter which one), then, apparently, this is only due to the fact that the plugin is either disabled or needs to be updated (update messages are sometimes disabled, especially when using optimizers that work online). In this case, you just need to update the required add-on or add-on, in particular, download the Flash Player plug-in from the official Adobe website, and then install it into the system after closing Opera.
It is likely that your online browser has installed a plugin such as AdBlock, which is sometimes also capable of blocking the content of Internet sites (often pop-up windows). If necessary, you can disable such a plugin in the add-on settings.
As you can see, there is no need to perform anything particularly complicated to eliminate the error in question. But these are only the general and most common causes of errors of this kind. Before deciding to use one action or another, it is important to clearly understand the current situation.
An SSL protocol error (ERR_SSL_PROTOCOL_ERROR) occurs when a user authenticates on sites that use data encryption. For example, a user tries to log into his VKontakte, Mail.ru or Google account, but instead receives error 107, and the required page does not open. There is nothing critical here, so we will analyze in more detail in the article what it means and how to eliminate it.
err_ssl_protocol_error: what does the error mean?
Error 107 indicates that the secure connection is being blocked. It’s quite difficult to say right away, since the SSL protocol error is not specified, but by following the troubleshooting recommendations, you will get rid of it.
Elimination methods
Since there is no specifics in the ERR_SSL_PROTOCOL_ERROR notification, we will consider the most possible options for solving the problem.
Antivirus scan
Windows 10 may have been infected by viruses or malware that disrupted the stable operation of the OS. I recommend using standalone scanners, such as the free Dr. Web CureIt or Kaspersky Rescue Disc. 
A date and time discrepancy between the computer and the site server can lead to error 107. The remote server has its own date and time settings, so the data is verified when connecting. If there is a discrepancy, the server will consider the connection attempt to be unsafe and block it. To check the date and time, go to the BIOS settings, change to current ones and restart the PC, saving the changes. 
OS update
Connection problems may occur due to the fact that the OS has not been updated for a long time. Run the latest Windows updates and check if it works. This is especially true for previous versions (Windows XP, Vista, 7). 
Advice! Check the entrance to the site you need through a different browser. This problem was not observed in Internet Explorer.
Setting up an encryption protocol in an antivirus
The problem may occur due to antivirus packages blocking SSL connections. To resolve this, disable checking the SSL and HTTPS protocols in your antivirus and try logging into the site. 
Firewall exception list
If you encounter the ERR_SSL_PROTOCOL_ERROR problem in Google services, a search engine, or in the browser itself, use the list of exceptions to personalize your security settings. Add the appropriate Internet application to the list of allowed sites. 
Important! Clear the cache and cookies in the browser (for example Google Chrome) that caused error 107.
If the problem still persists, . Please indicate when it occurred and what operations you have already performed so that we can help.
Almost every user has encountered many problems in the browser. One of these problems is SSL connections, which does not allow you to view the necessary pages. Let's look at all the ways to fix this problem.
First stage
So, first you need to decide what kind of problem it is, where it comes from, and only then look for ways to fix it. If an SSL connection error appears on your computer when you try to connect to any page on the Internet through a browser, this indicates that the problem is caused by a mismatch in the system. Therefore, this needs to be corrected, but, as practice shows, this is not as easy as it might seem at first glance.
Often all installed browsers refuse to work. 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. Let's figure out what causes this kind of problem.
Causes of SSL Errors
So, there are often only a few ways to find out what exactly is preventing you from accessing the Internet normally. So, the first thing you need to do is check the settings of your antivirus, since it is it that 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. It is also recommended to check if necessary, lower the protection level.
Also at Google, an SSL connection error 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. Also note that your time settings may be incorrect. Consequently, a discrepancy is detected on the server, and the connection is determined to be unreliable or insecure. Another common reason is an outdated browser.
SSL origin connection error
If you like to play good games on your computer and buy them online, then most often such a product requires activation. Even though this is a minute process, it can become a real headache for you due to SSL protocol failure. However, the detailed error text may look different. For example: “client authentication certificate required” or “SSL_ERROR_PROTOCOL”. You can fix everything as follows.
We go into the antivirus, if, of course, it is available. Next we go to the settings, to be more precise, we need the line “https protocol filtering”. Here you need to uncheck the box, that is, turn it off. Reboot the computer and try to install origin. If everything went well, then if not, it is advisable to install the game from the disk and just try to update it. What else can help is using a different browser, for example, not Chrome, but Opera.
SSL connection error: fixing the problem
Let's figure out what to do if this kind of problem arises. First of all, there is no need to panic. It’s not all that scary and can be resolved in a few minutes. The main reason for the error is that, as noted above, this happens for several reasons. One of them is a dead battery in the BIOS. It can be changed, it costs 40-50 rubles.
We also pay attention to the antivirus and the list of programs that are on the blacklist. It will block the connection of these applications. It is worth noting that a broken registry can often be the cause of the problem. Most users rack their brains to solve the problem, but sometimes it happens that this is not an error at all. The fact is that most browsers allow you to enable or disable support for SSL files. Just find the required option in the settings and check the box, after which the problem should be solved.
Enable SSL and Cookies in the browser
In some cases, this protocol is not required. But when you want to use Adsense pages, this option must be enabled. The same applies to Cookies. In principle, for normal operation and display of information, incl. and advertisements, you need a working SSL. So, let's move on to setting up the browser. First of all, you need to go to the menu, and then select settings.
There you should see the “Advanced Settings” tab, this is what we need. The next step is to select the “Content Settings” item, and then you need to go to “Personal Data”. We will see a menu called “Cookies”. We go there and check the box next to the “Save local data” item. Close the tab and switch to HTTPS/SSL. Similar work needs to be done here. Check the box next to “Check if the certificate has been revoked from the server.” If the checkbox is not checked, then SSL will not work correctly. That's all, restart the browser and get to work.
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 the Windows folder, then system 32, and then to 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.
A few important points
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.
Conclusion
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 the desktop tray of your 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 an antivirus program or a malicious file that is blocking the connection. Removing or moving to quarantine should help.
One of the problems that a user may encounter when surfing the Internet through the Opera browser is an SSL connection error. SSL is a cryptographic protocol that is used to verify the certificates of web resources when accessing them. Let's find out what could be causing the SSL error in the Opera browser, and what methods can be used to solve this problem.
First of all, the cause of such an error may actually be an expired certificate on the side of the web resource, or its absence. In this case, it's not even an error, but the browser providing real information. The modern Opera browser in this case displays the following message: “This site cannot provide a secure connection. The site sent an invalid response."
In this case, nothing can be done, since the fault is entirely on the site’s side.
It should be noted that such episodes are isolated in nature, and if you get a similar error when you try to access other sites, then you need to look for the source of the cause elsewhere.
Invalid system time
One of the most common causes of SSL connection errors is incorrectly set time in the system. The browser checks the validity period of the site's certificate against the system time. Naturally, if it is set incorrectly, then even a valid certificate will be rejected by Opera as expired, which will cause the above error. Therefore, if an SSL error occurs, be sure to check the date set on the system in the system tray in the lower right corner of the computer monitor. If the date differs from the real one, then it should be changed to the correct one.
Left-click on the clock, and then click on the inscription “Change date and time settings.”
It is best to synchronize the date and time with a server on the Internet. Therefore, go to the “Internet Time” tab.
Then, click on the “Change settings...” button.
But, if the gap between the date set in the system and the real one is very large, then it will not be possible to synchronize data in this way. You will have to set the date manually.
To do this, go back to the “Date and Time” tab and click on the “Change Date and Time” button.
A calendar opens in front of us, where, by clicking on the arrows, we can navigate through the months and select the desired date. After the date is selected, click on the “OK” button.
This way, the date changes will take effect and the user will be able to get rid of the SSL connection error.
Blocking by antivirus
One of the reasons for an SSL connection error may be blocking by an antivirus or firewall. To check this, disable the antivirus program that is installed on your computer.
If the error repeats, then look for a different reason. If it disappears, then you should either change your antivirus or change its settings so that the error no longer occurs. But this is an individual question for each antivirus program.
Viruses
Also, the presence of malware on the system can cause an SSL connection error. Scan your computer for viruses. It is advisable to do this from another uninfected device, or at least from a flash drive.
As you can see, the reasons for an SSL connection error can be completely different. This can be caused either by a real expired certificate, which the user cannot influence, or by incorrect settings of the operating system and installed programs.
Today we will look at and solve a fairly popular problem with browsers when working with SSL certificates: when the browser, when accessing a certain site, throws an error, informing us that it is unsafe...
Often this is not a serious threat - more often, these are errors in outdated browsers (not updated) or some temporary errors in the ssl certificates themselves (between the company issuing the SSL and the browser). An example for solving a problem is the Mozilla Firefox browser, although Google Chrome and others are often tricky (but the principle of the solution is the same!).
Well, let's find out in more detail and look at how to fix the error sec_error_revoked_certificate in Mozilla Firefox.
how to fix sec_error_revoked_certificate
The ssl error when accessing the site looks like this:
An error occurred while connecting to DOMEN.ru. The peer certificate has been revoked. Error code: SEC_ERROR_REVOKED_CERTIFICATE
Description of the secure connection error
Users usually solve similar errors like this:
1 - They leave the selected site (this is not at all necessary!) because, as mentioned, most often THIS is an error of the certificate provider or the browser)
2 - Clean the cache, cookies... or correct others... by scanning CCleaner with programs.
3 - Reinstall (or update the Mozilla Firefox browser)
However, the current connection error with the site sec_error_revoked_certificate in Mozilla Firefox is non-standard - that is, it does not depend on cookies and other user data, and therefore the steps to solve this problem are somewhat different.
Benefits for:
The error indicates a discrepancy between the digital signatures of SSL sites and the security keys on the local computer (that is, with the recorded certificate data in the browser kernel / settings / for a given period of time)
...and therefore, I think it’s hardly worth delving into the causes and solutions to this problem, but it’s easier to solve the problem and forget:
how to fix secure connection error
Open your browser settings! (screen below)
Path: “Tools” - “Settings” - “Privacy and Security”.
If you do not have the toolbar enabled, turn it on: in an empty space of the browser window (somewhere at the very top), right-click and select “Menu Bar”.
In the privacy and protection options... scroll to the very bottom of the page and look for the following settings:
We will need the “Certificates” section of the Mozilla Firefox browser to fix the sec_error_revoked_certificate error.
Uncheck the box “Request OCSP servers to confirm the current status of certificates”...
Do you understand, right!? The settings from those shown in the screenshot may differ slightly visually in different versions of the browser, this is not a big deal - it doesn’t matter what version of Firefox you have - the main thing is to find the “Certificates” option!
Having completed these simple settings, the annoying error sec_error_revoked_certificate will disappear from us...
After viewing the required site, the checkbox can be returned: entirely at your discretion.
