Sometimes, the computer which you are using might not be able to make connection with the website. Most of the websites use the SSL certificate in order to provide a security layer. There are certain things on a website which might be insecure without an SSL certificate like credit card processing, password processing, etc.
The error statement faced might look something similar to this: A secure connection cannot be established because this site uses an unsupported protocol. Error code: ERR_SSL_VERSION_OR_CIPHER_MISMATCH
When a user tries to visit a website, the browser automatically downloads the SSL certificate in order to securely connect to the website. Sometimes, what happens is that when the SSL certificate is download on your computer, it is the culprit of misconfiguration or malfunction and all the values in the certificate get messed up because of that. The error code ERR_SSL_VERSION_OR_CIPHER_MISMATCH is displayed when that happens and the website will become inaccessible to the user. There are a good amount of fixes which we have devised in order to get rid of these errors.
There are some things you must do in order to move forward:
- Try visiting multiple websites and make sure whether you are able to visit the ssl enabled (https) websites. If you can do it, the problem you are facing might not be server sided.
- Delete all the cache files as well as cookie files from your browser so that you can verify if they are the problem or not.
- All the extensions which you are using must be disabled and you must check whether the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error goes away after that. If it did go away, you can enable them one by one in order to check if there is an extension which is responsible for this.
- Make sure that you or any third party application did not mess with the firewall. There are chances that your firewall is blocking you from visiting the websites because you might have blocked something sensitive.
- Check if the data connection you are using is working properly. If not, contact your network provider because they are the only ones who can solve these problems.
We have created a fully fledged guide with multiple fixes just for you. Different computers use different configurations and the difference in those configurations might lead to different root causes. Make sure you follow all the fixes so that you do not need to jump from one thread to another and waste your time trying your luck.
Make sure to create a restore point before you follow the fixes because in case there are more problems raised due to misconfigurations, you can always turn back time and restore your system to the way it was.
