ERR_SSL_VERSION_OR_CIPHER_MISMATCH in Chromium [SOLVED]: The main cause of this error is that your computer cannot determine a private connection with the web portal. The web portal is using an SSL certificate which is causing this error. The web portal is using an SSL certificate that processes sensitive information such as credit card information or passwords.
A secure connection cannot be determined because this site uses an unsupported protocol. Error code: ERR_SSL_VERSION_OR_CIPHER_MISMATCH
As long as you use the aforementioned web portal, your browser downloads the Secure Sockets Layer (SSL) security certificates from the web portal to determine a secure connection, but from time to time the downloaded certificate is corrupted or your computer settings do not match that of the SSL certificate. In this circumstance, you will see ERR_SSL_VERSION_OR_CIPHER_MISMATCH error and you may not be able to enter the web portal, but don't worry, we have listed some methods that will help you to fix this problem.
It is a prior requirement:
- Check if you can enter another Https-enabled web portal because if so, then there is an obstacle with that particular web portal, not with your computer.
- Make sure you have cleared the caches and cookies on your computer.
- Remove unnecessary chrome extensions that could be causing this problem.
- Proper connection to Chrome is allowed through Windows Firewall.
- Make sure you have a proper internet connection.
