Your browser will automatically examine the SSL certificate of any website you try to link to every minute. It’s a technique of ensuring that the website you’re visiting is genuine and that the right protocol was utilised to protect your connection.

The Handshake protocol is what it’s called. TLS (Transport Layer Security) is a technology that encrypts data exchanged between a user’s machine and a web server.

Assume that neither the user’s browser nor the web server supports a common SSL protocol and cypher suite during the TLS handshake. The browser displays the error message ERR_SSL_VERSION_OR_CIPHER_MISMATCH when this happens.

This website refuses to provide a network connection for a variety of reasons. The following are some of the most likely reasons:

Invalid SSL certificates – A certificate mismatch can occur when a domain’s SSL certificate is assigned to a separate website domain alias. Web browsers that are no longer supported – The latest TLS version may not be compatible with older operating systems and web browsers.

The QUIC protocol is a Google project that can be used to replace common security measures, but it has the potential to produce the error. A web browser’s cache — the cached data may or may not reflect a website’s security upgrade.

Antivirus software – a flaw in antivirus software can result in a false warning, resulting in the loss of data.

The ERR_SSL_VERSION_OR_CIPHER_MISMATCH problem is simple to fix, despite its convoluted and daunting appearance to beginners. The ERR_SSL_VERSION_OR_CIPHER_MISMATCH issue has six possible remedies.

1. Clear the SSL State 

If you still can’t establish a secure connection with Chrome, you should try removing the SSL state. Follow these methods to verify the SSL status in your browser on Windows:

Step 1: Open Google Chrome and navigate to the Settings icon (Settings) icon. Select Show advanced settings from the drop-down menu.

Step 2: Go to Network and change your proxy settings. The dialogue box for Web Properties appears.

Step 3: Navigate to the Content tab.

Step 4: After selecting Clear SSL state, click OK.

Step 5: Restart Google Chrome.

2. Enable SSL/TLS Versions 

Please keep in mind that permitting outdated, unsecure protocols is part of this process. This is done solely at your own risk.

Step 1: To begin, open Chrome.

Step 2: In the upper-right corner, right-click the dots.

Step 3: Next, go to Settings and search for “proxy” in the search area.

Step 4: If the Open proxy options menu appears, select it.

Step 5: Select the Advanced option from the drop-down menu.

Step 6: Now is the time to mark all SSL and TLS versions.

Step 7: Press the Apply key.

Step 8: Close and reopen Google Chrome.

 3. Examine Your Internet Connection

This issue is typically caused by a bad internet connection. Check your internet service to make sure it’s working properly, and contact your Internet Provider if you need help.

4. Examine the SSL Certificate 

When the client and server don’t have the same SSL protocol version and cypher suite, one of the first things you should do is examine the SSL certificate.

Chrome allows you to view certifications as well as conduct in-depth investigation and evaluation of free online resources. The one provided by Server SSL Labs is the one we suggest.

 5. Clear the Cache and Cookies in Your Browser

One of the first things you should do if you get a web error is erase your browser cache and cookies, as these are typically the source of all kinds of issues.

Depending on the internet browser you’re using, this step may differ. Because you’ve never done this before and are unclear how to continue, use a search engine to look up the steps required to erase the data from your preferred internet browser.

In some circumstances, pressing CTRL + SHIFT + DELETE will take you to a website where you can wipe your web browsing data.
