If you’ve don’t even know about the term SSL, then SSL Certificates is basically a website security system which can provide you a secure, encrypted connection between the website and the website’s users. Basically, the word “SSL” stands for “Secure Sockets Layer” and it’s a protocol which is only made to encrypt online connections.

Most of the people having this problem while accessing the bank websites or maybe while doing some online transactions, and sometimes not just only bank website, users also having this problem while surfing anything on the internet and it’s also possible that your own website is having this issue lately.

But the thing is, now you really don’t have to worry about it because with the help of this article, I’m going to help you out to fix this problem by your own.

#Troubleshooting Computers Setting

When you surf the Internet on any browser on your computer, it downloads the Secure Sockets Layer (SSL) security certificates from those websites who uses this SSL Security and this process called Caching SSL Certificates.

Sometimes when a corrupted certificate get saved by your browser, it’s quite possible that you having this problem shown on our browser.

However, to fix this issue there are some options you can try to make everything back to normal, the all the things what I’m talking about includes, turning some feature OFF and clear all the saved Cache Certificates stored in your computer.

So, let’s see which solution works on your computer.

@Changing Security Setting In Chrome:

To change the security setting in your chrome browser, first you’ll need to open it and type this Url “chrome://flags” without quotes into your browser’s address bar and by doing that your browser will open your chrome’s internal hidden settings page in front of you.

In that page, I want you to find the option named “Minimum SSLv3 version support” and change its setting to “SSLv3”, and after that restart your computer and test your internet connection.

If you can’t able to find this setting in your chrome’s setting page or maybe making changes in that setting won’t works for you, in that case, you  still have more solutions to try and now you’ll just need to stick with this tutorial and move to the next one listed down below.

#Troubleshooting Own Website

It’s common to having this problem on your website and mainly this error only occurs on those websites who using SSL security certificates to encrypt their connection between a user and the website.

If you see this error on your website, then it means that the secure connection can’t be able to establish on a browser because of some outdated security code on your website. Chrome is just protecting the user’s privacy by preventing the page to open.

If you use any kind of CND Service for yore website then it’s also quite possible to have this problem on your domain and you can quickly confirm it by turning off your CDN Service for a while just for testing purpose.

If you’ve recently installed the SSL Certificate on your server then I’ll highly suggest you check every configuration again what you’ve recently done.

If you can’t find anything useful for your website, then the last and best way to fix this “ERR_SSL_VERSION_OR_CIPHER_MISMATCH” Error on your website is by calling your hosting provider.
