entranceCheck the coverage in tel 005. Eliminating the error when establishing a secure connection in Mozilla Firefox
Due to the increasing blocking of web resources, everything more users have to face access errors. However, they may not always be associated with blocking sites by providers, the problem may be hidden on the computer itself. This is an error, and it doesn't matter which browser is used.
An error may occur due to the absence of a certificate for the site confirming the safe operation of the browser with this site. SSL , also the reason for its appearance may be associated with changes in the settings software responsible for the security of the system. Today we will look at one of the most common variants of the above error, in which the user receives a notification "Site "URL" posted an invalid reply. ERR_SSL_PROTOCOL_ERROR " .
With a greater degree of confidence, we can say that everything is in order with the site itself, however, check its availability using some service like ping-admin.ru doesn’t hurt either. If the resource is available, you should look for the causes of the error on the computer. There may be several reasons. If the site is using a connection HTTPS first, you can check if the protocols are enabled SSL2 and SSL3 in browser properties. Open the classic control panel, run the applet.
Switch to tab "Additionally" and make sure that in the checkboxes SSL 2.0 and SSL 3.0 checkboxes are installed.
At the same time, check if the time on a PC with your time zone. If not, expose right time and enable sync.
Alternatively, you can try to disable protocol filtering. HTTPS , although it is undesirable to do this, as this reduces the level of security. In, for example, this can be done as follows. Go to the internal address chrome: // net-internals / # hsts , from the menu on the left, select HSTS, in field "Delete Domain" insert the address of the problem site without the prefix HTTPS and press "Delete".
After that, you will be able to enter the site using the usual protocol. HTTP .
Note: before making changes to the protocol processing settings, you must completely clear the browser cache and delete the saved files cookies and then try to go to the site. If the entry is made without errors, with filtering off HTTPS you can not rush.
It is very likely that access to the site is blocked by the installed on the computer antivirus software... Sometimes the reason for the error becomes apparent after enabling in the browser private mode (incognita)... Here, for example, what shows when going to a blocked site in incognito mode. In this case, the error "This site cannot provide a secure connection." calls antivirus .
Therefore, you need to either disable real-time protection in this program, or add the blocked site to the list of exclusions.
The settings of other antivirus software are checked in the same way. In particular, users had to deal with the described error. Dr.Web (firewall settings) and ESET NOD32 (setting "Filtering SSL / TLS protocols") ... At the same time, it is necessary to check the work of the extensions installed in the browser, since some of them, in particular, SaveFrom.net may interfere with the normal operation of network resources. And the last thing. If you get an access error when opening the site, use the most common anonymizer, or even better VPN -service, in most cases, these tools allow you to bypass such restrictions.

Considered the most stable browser, some users may encounter various errors during use. This article will discuss the error "An error occurred while establishing a secure connection", namely, how to fix it.
The "Error while establishing a secure connection" message can appear in two cases: when you go to a secure site and, accordingly, when you go to an unprotected site. We will consider both types of problems below.
In most cases, the user encounters an error while establishing a secure connection when going to a secure site.
The fact that the site is protected, the user can tell "https" in address bar before the name of the site itself.
If you are faced with the message "An error occurred while establishing a secure connection", then below it you can see an explanation of the cause of the problem.
Reason 1: The certificate will not be valid until the date [date]
When you go to a secure website, Mozilla Firefox necessarily checks the site for certificates, which will make sure that your data will only be transferred to where it was intended.
As a rule, this type of error indicates that the wrong date and time is set on your computer.
In this case, you will need to change the date and time. To do this, click on the date icon in the lower right corner and select the item Date and time options .
Reason 2: Certificate expired [date]
This error can also indicate an incorrectly set time, and it can be a sure sign that the site has not renewed its certificates in time.
If the date and time is set on your computer, then the problem is probably in the site, and until it renews the certificates, the site can only be accessed by adding to the exclusions, which is described near the end of the article.
Reason 3: the certificate is not trusted because its issuer certificate is unknown
This error can occur in two cases: the site is really not worth trusting, or the problem lies in the file cert8.db located in the folder of the Firefox profile that has been corrupted.
If you are confident in the safety of the site, then the problem is probably still damaged file... And to solve the problem, you need Mozilla Firefox to create a new such file, which means you need to delete the old version.
To get to the profile folder, click on the Firefox menu button and in the window that appears, click on the icon with a question mark.
An additional menu will be displayed in the same area of the window, in which you will need to click on the item "Information for problem solving" .
In the window that opens, click on the button Show folder .
After the profile folder appears on the screen, you need to close Mozilla Firefox. To do this, click on the browser menu button and in the window that appears, click on the button "Output" .
Now let's go back to the profile folder. Find the cert8.db file in it, right-click on it and select "Delete" .
Once the file is deleted, you can close the profile folder and start Firefox again.
Reason 4: there is no trust in the certificate, because missing certificate chain
A similar error occurs, as a rule, due to antiviruses in which the SSL scanning function is activated. Go to your antivirus settings and disable the network (SSL) scan function.
How to fix the error when going to an unsecured site?
If the message "An error occurred while switching to a secure connection" appears, if you go to an unsecured site, this may indicate a conflict between settings, add-ons and themes.
First of all, open the browser menu and go to the section "Supplements" ... In the left pane of the window by opening the tab "Extensions" , disable the maximum number of extensions installed for your browser.
Next go to the tab « Appearance» and remove all third-party themes, leaving and applying the default for Firefox.
After completing these steps, check for an error. If it persists, try disabling hardware acceleration.
To do this, click on the browser menu button and go to the section "Settings" .
In the left pane of the window, go to the tab "Additional" , and at the top open the sub-tab "General" ... In this window, you need to uncheck the box "Use hardware acceleration whenever possible" .
Workaround the error
If you are still unable to resolve the "Error establishing secure connection" message but are confident that the site is safe, you can bypass the persistent Firefox warning to fix the problem.
To do this, in the window with an error, click on the button "Or you can add an exception." , then click on the button that appears "Add an exception" .
A window will appear on the screen in which click on the button "Get a certificate" , and then click on the button "Confirm Security Exception" .

We hope this article helped you fix the problems in how Mozilla works Firefox.
Sometimes, and quite often, users, when trying to enter a certain Internet resource, receive a message that an error occurred while establishing a secure connection. How to fix such a failure will now be considered. Several different techniques can be used depending on the situation.
What does it mean: "An error occurred while establishing a secure connection"?
First of all, you should clearly understand the very problem of such a failure. The essence of the error is that the system, when accessing a specific site, needs to check the SSL certificate used for HTTPS connections in order to establish the authenticity of the publisher.
However, it is possible to clearly identify several situations when such a check gives a negative result, as a result of which a message is displayed that an error occurred while establishing a secure connection:
- inconsistency of the date and time on the computer with the Internet parameters;
- outdated or expired certificate;
- a certificate with an incorrect serial number;
- OCSP server errors;
- incorrect browser settings (most often Mozilla Firefox);
- blocking by antivirus.
Let's consider a few typical situations.
Error while establishing a secure connection: how to remove it in the simplest way?
Let's start with the most basic troubleshooting method. As mentioned above, the time set on the computer may not correspond to the parameters of the Internet. Therefore, these settings need to be changed.
Some users try to set the date and time directly in Windows, this does not give the desired result, and the error when establishing a secure connection appears again. Why? Yes, only because the configuration needs to be done in the primary input / output system BIOS. Then you can still count on something.
Disabling SSL and installing a certificate in antivirus
Antivirus versus firewall or windows defender are much more likely to block such connections, considering the connection to be invalid.
The solution to the problem can be either a temporary disabling of protection, which is not very convenient, or setting the appropriate parameters. Typically, this section is located in the network settings. Here you need to disable SSL verification, and then use the "Certificate Installation Wizard", which will evaluate the validity of the connection, after which you just need to install the certificate. After confirming successful installation, the problem should be gone.
Correcting an error in browsers using the example of Mozilla Firefox
Browsers are a little more complicated. As a rule, the message that an error occurred while establishing a secure connection is most often given by the "fire fox".
The situation can be corrected as follows. First, with the browser disabled, go to the "Explorer" in your profile set for the browser (the profile folder is located on system disk in the directory with the username of the Users directory, where you need to go to the AppData directory, then - Roaming, then - Mozilla, then - Firefox, after that - Profiles, finally -
Note: in addition, in the security parameters of tls_tickets by double-clicking, you can change the parameter value to false. Just in case, you can check if the blocking extension AdBlock is enabled.
Problems with torrent trackers
As you know, the governments of many countries do not pamper torrent trackers, believing that only pirated content is posted on such sites. This is partly the case, but not always. One of these resources is the NNM.Club tracker. An error when establishing a secure connection appears on it quite often.
The tracker itself is now serviced exclusively at two addresses - 81.17.30.22 and 193.201.227.16. If something else is returned when pinging the address, it means that a spontaneous redirection occurs. In this case, you just need to clean DNS cache, see if there are any entries for these addresses in HOSTS file at the very bottom of the text, finally, you can simply set exclusion rules for these IPs in the antivirus or in the firewall.
As a last resort, if it is problematic for an ordinary user or the solution does not help, instead of a torrent file, you need to download the so-called magnet link and run it in the corresponding torrent program. Basically, the same goes for other trackers as well.
