ERR_SSL_VERSION_OR_CIPHER_MISMATCH, Is that what are you dealing with right now?

If you’re trying open a particular website and the site is not loading any contents and if it keeps throwing you back with an error then it can cause a question in the head to see if there is any trouble in the system to why it isn’t allowing you to process through. It may be irritating at times, let’s decode few things about the same and see what can be done if the same.

The ERR_SSL_VERSION_OR_CIPHER_MISMATCH is actually the error you receive when you’re trying to visit a website and the website throws you back with an error of ‘This webpage is not available’.


The basic reason for the ERR_SSL_VERSION_OR_CIPHER_MISMATCH can be:

  • Website is blocked and not functional
  • Firewall having a blocked status for the certificate/website
  • Poor internet connectivity
  • If caches & cookies are not cleared
  • Add-ons or extensions that may implement some blockage for the websitegoogle

Usually, this error only occurs when there is a trouble that your system is facing in terms of being connected to the private connection on a secured website. This error is also related to the SSL certificate security that allows your system to securely connect to the website, basically working as a website security system. The name stands for ‘Secure sockets layer’ which enables the system to be connected to a particular website without any error followed on the same. In case if this certificate is unavailable, you may see the same error while visiting any website.

There are times when you may face this trouble then or unwanted certificate have been downloaded on your system that restricts other application to function properly.

The initial check on the same shall be done if the certificate game has been mismatched to control the website content. In this specific case, the client moving to Kinsta had an authentication name crisscross which was hurling the ERR_SSL_VERSION_OR_CIPHER_MISMATCH blunder. As should be obvious from the SSL Labs test beneath, this is really snappy and simple to analyze. As SSL Labs expresses, a confound can be various things, for example,

  1. When the site does not support the SSL certificate

2. In case if the site is not working anymore and the domain is still active yet non-functional.

3. If the site has the CDN cert that doesn’t qualify the SSL to function on the website

4. If the web address has been incorrectly put and lands you on the page that doesn’t exist.
