Every minute you try to link to a website, your browser will automatically check its SSL certificate. It’s a way to verify that the website you’re visiting is legitimate and has used the proper protocol to protect your connection.
This is known as the Handshake protocol. TLS is a protocol that encrypts data sent across a user’s computer or a web server. Assume that during the TLS handshake, both the user’s browser & the web server do not assist a common SSL protocol and cypher suite When this happens, the browser displays the error message saying ERR_SSL_VERSION_OR_CIPHER_MISMATCH.

What Causes The ERR_SSL_VERSION_OR_CIPHER_MISMATCH?
For a number of reasons, this website refuses to offer a network connection. One of the most likely reasons are:
Invalid SSL certificates – Domain’s SSL certificate may have been assigned with different website domain alias, resulting in a certificate mismatch.
Outdated web browsers – Older operating systems and web browsers may not be suitable with the latest TLS version.
The QUIC protocol is a Google project that serves as a substitute to common security solutions, but it may cause the error.
The cache of a web browser – the cached data may well not reflect the website’s security update.
Antivirus software – a malfunction in the antivirus software may cause a false alarm, resulting in the
How To Fix The ERR_SSL_VERSION_OR_CIPHER_MISMATCH Error
Despite its complicated & intimidating appearance to beginners, the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error is simple to resolve.
Let’s look at six solutions to the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error.
Method 1: Clear The SSL State
Removing the SSL state is another thing you should try if you can’t create a strong connection with Chrome. To check the SSL state through Browsers on Windows, perform the following steps:
Step 1: Then, click the Google Chrome and go to Settings icon (Settings) icon. Click the Show advanced settings button.
Step 2: Change proxy settings can be found under Network. The Web Properties dialogue box appears.
Step 3: Go to Content tab.
Step 4: Click OK after selecting Clear SSL state.
Step 5: Chrome should be restarted.
Method 2: Enable SSL/TLS Versions
Please keep in mind that this step includes allowing older, insecure protocols. You do this entirely with your own risk.
Step 1: Launch Chrome.
Step 2: Right – click dots in the upper-right corner.
Step 3: Then go to Settings & type ‘proxy’ into the search field.

Step 8: Restart Google Chrome.
Method 3: Check Your Internet Connectivity
A defective internet connection is frequently to blame for this error. Check your internet service to ensure that everything is working properly, & inform your Internet Provider if you require assistance.
Method 4: Examine The SSL Certificate
When the client or server do not support the same SSL protocol version and cypher suite, one of the very first things you need to do is check the SSL certificate.
Chrome allows you to view certificates and perform in-depth analysis and assessment of free online tools. We recommend using the one supplied by Server SSL Labs.
Method 5: Delete Browser Cache and Cookies
When you experience a web error, one of the very first things you need to do is clear your browser cache and cookies, as these are frequently the source of all kinds of problems.
This step may vary based on the internet browser you use. Since you’ve never done this earlier & are unsure how to proceed, search engine for the actions needed to clear the data stored on your preferred internet explorer.
In some cases, pressing CTRL + SHIFT + DELETE would then take you to the clear web surfing data page.

Conclusion
If none of the above fix’s work, you could always try to install the internet browser and the extensions that are enabled in it. Please remember that maybe you are using an older operating system, you must consider upgrading although some of the new systems, such as TLS 1.3 and the latest cypher suites, are not endorsed in several of the older systems, such as Windows XP & similar.
