In the window that appears, click Show Certificate > Details.Double-click the padlock icon in the upper-right section.In the Inspection pane near the top, click the arrows > to reveal more options.To manually inspect your SSL Certificate, open the browser, load your webpage, and follow these steps: If you cannot completely disable RC4, add the TLS 1.3 protocol so that modern browsers don’t trigger the err_ssl_version_or_cipher_mismatch error. The best solution is to move the site from RC4 to TLS 1.3 protocols. If a website is configured to use RC4, an error may occur. Some organizations still use RC4 for legacy applications, but most modern browsers do not support it. It has been found to have significant vulnerabilities. RC4 Cipher is an old and simple tool for encrypting traffic. If your server is not configured to use TLS 1.3, consider updating to the latest protocol. Most modern browsers are set to use the latest version of TLS (if available on the website). If your site is running an older version of TLS, it may cause the CIPHER_MISMATCH error. The current version (at the time this article was written) is TLS 1.3.
TLS stands for Transport Layer Security and is a security protocol that’s used to encrypt communications between websites. Once you determine the source of the problem, you can resolve the issue easily.
The site has a domain name alias that is not in the certificate.The site uses a CDN (Content Delivery Network) that does not support SSL.The old website doesn’t exist, but another website has the first domain’s old IP address. The domain points to an old IP address it no longer uses.When the domain does not use SSL, but another domain with the same IP address uses SSL.There are a few reasons the names might not match, which can generate the error ERR_SSL_VERSION_OR_CIPHER_MISMATCH: Additionally, the certificate must come from a trusted provider. The website name and the name on the certificate must match. Check for Certificate Name Not MatchingĪn SSL certificate proves that your website is who it claims to be. We recommend using a dedicated tool, such as the Qualys SSL Labs tool we mentioned. This method should be used only for a quick reference.
