So, let’s get started without any further details.
What Is the ERR_SSL_VERSION_OR_CIPHER_MISMATCH Error?
The ERR_SSL_VERSION_OR_CIPHER_MISMATCH error is a common SSL-related error that occurs when a website’s SSL/TLS certificate does not match the encryption protocol or cipher that the browser is trying to use to establish a secure connection.
In the following sections, we will have a look at chrome err_ssl_version_or_cipher_mismatch causes and how you can fix them with some effective and proven-to-work techniques.
What Causes the ERR_SSL_VERSION_OR_CIPHER_MISMATCH Error?
There are several reasons why you might encounter the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error. We have given a brief about each of the causes for your reference.
Outdated TLS Versions:
One of the most common causes of the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error is outdated TLS versions. If your browser tries to use an outdated version of TLS to establish a secure connection with a website that only supports newer TLS versions, the connection will fail.
To fix err_ssl_version_or_cipher_mismatch Chrome because of an outdated TLS version, you can update your browser to the latest version, which should support the latest TLS versions.
Another common cause of the net::err_ssl_version_or_cipher_mismatch error is an invalid or expired SSL/TLS certificate. If your browser does not trust the website’s certificate or it has expired, it will not be able to establish a secure connection with the website.
To fix this issue, you can try clearing your browser cache or contact the website’s owner to request a new, valid SSL/TLS certificate.
Sometimes, the chrome err_ssl_version_or_cipher_mismatch error can be caused by a corrupted or outdated browser cache. If this is the case, clearing your browser cache and cookies should fix the issue. You can do this by going to your browser’s settings and clearing your cache and cookies.
Outdated OS or Browser:
If your operating system or browser is outdated, you may encounter the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error. In such cases, errors occur because older operating systems or browsers may not support newer versions of TLS. You can try updating your operating system or browser to the latest version to fix this issue.
The next reason for getting “uses an unsupported protocol” when accessing a website can be the antivirus software you use. To fix this issue, you can try temporarily disabling your antivirus software and see if the error disappears. If it does, you may need to add an exception for the website in your antivirus software.
Finally, the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error can be caused by using the QUIC protocol. It is a new protocol still in development and may not be supported by all browsers.
To fix this issue, you can try disabling the QUIC protocol in your browser’s settings.
Now as we know why you may get a “uses an unsupported protocol” message while browsing through websites, let’s have a look at various ways of chrome err_ssl_version_or_cipher_mismatch.

Clearing the SSL state in Chrome will remove any corrupted or outdated SSL/TLS information that may be causing the error.
To clear the SSL state in Chrome, go to Chrome’s settings, click on “Privacy and Security,” then select “Clear browsing data.” Check the box next to “Cookies and other site data” and “Cached images and files,” then click on “Clear data.”
Check for Certificate Name Mismatch:
Another common cause of the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error is a certificate name mismatch.
The mismatch of certificate names occurs when the domain name in the SSL/TLS certificate does not match the domain name of the website you’re trying to access.
To fix this issue, double-check the domain name in the certificate and ensure that it matches the website’s domain name.
Configure SSL with Cloudflare:
Another reason for err_ssl_version_or_cipher_mismatch Cloudflare is configuration. If you’re using Cloudflare to manage SSL/TLS for your website, you may need to configure it correctly to avoid the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error.
