If you present the problem ERR_SSL_VERSION_OR_CIPHER_MISMATCH it is because your browser has detected a website as a threat.
Basically because it believes that it is not a secure page, this message usually appears on websites that request personal data or those whose security certificate cannot be verified.
It is a guarantee of reliability between the connections of the server and the browser, when a page does not meet this requirement, it is very likely that it will not be shown to you to prevent an unfortunate event.
There are also the sites that handle a number of outdated protocols which are currently considered unsafe.
But let’s say that you need to access a website yes or yes, in this case I am going to explain the steps you can follow to achieve it.
Steps to fix ERR_SSL_VERSION_OR_CIPHER_MISMATCH error
First of all, you should be aware of what it would mean to get rid of this error, practically you would be at the mercy of an attack via malware.
My recommendation is that you first make sure that the site you want to enter is totally safe.
Because it makes no sense to sacrifice your security by entering a website blindly, with this in mind, let’s see the 4 methods that you can apply.
Check your SSL/TLS certificate
The first thing you should do is check the status of your SSL/TLS because if it is old it is normal for these errors to appear, to check it you have to go to .
This tool will allow you to check the status of your SSL certificate and will score your SSL connection with the server, indicating if there is any kind of improvement or if you need to update your SSL/TLS.
TLS 1.3 support
TLS will help you to have a secure connection between browser and web server. If you have this function disabled, it would explain why your browser would be rejecting some SSL certificates from some websites.
For enable it You just have to follow a few simple steps:
- Opens Google Chrome.
- Type chrome://flags in the Chrome URL bar and Enter.
- Search TLS.
- Sets support for TLS 1.3 com “Enable”.
Remember that you will have to have the latest version of google chrome to activate it.
Ok, open a new Google Chrome tab and follow these steps:
- Go to the top bar of the browser, paste the following, press enter: chrome://flags.
- Here you need to find and click the Minimum SSL/TLS version, then choose SSLv3, restart, and then proceed to restart the browser.
Disabling the Quic protocol
In this procedure you must also open a new Chrome window.
- Go to the top bar and paste the following: chrome://flags/#enable-quic and press enter.
- Next, you will go to a section where you only have to disable the first option and restart the browser.
Disabling antivirus SSL scanning
If you use an antivirus to protect your computer, the most common thing is that it blocks the pages that it considers insecure.
To fix it, you have to go to the SSL scanning feature and disable the option.
In each antivirus the process is different, so you will have to review a little or look for information about it.
