Potential Causes of the “SSL_ERROR_NO_CYPER_OVERLAP” Error
Firefox may also display the message that the “authenticity of the data cannot be verified” along with the error message. If so, the message might also suggest getting in touch with the website’s owner. Although the problem might be with the website, it might also be a problem with the browser.
More specifically, there’s a chance that the website and your computer aren’t communicating properly because of your version of Firefox or a particular browser setting. TLS or SSL3 settings that have been disabled or incorrectly configured are another possible factor. Additionally, in order to connect, the server and your browser must select the same encryption cypher.
Due to vulnerabilities, some cyphers, like RC4, are no longer supported by popular browsers. You might encounter this error if the website’s server employs an unsupported encryption technique. This error has reportedly been experienced by some users after installing Cloudflare. The reason it usually happens is that the browser isn’t compatible with the Server Name Indication (SNI) protocol, which is what Cloudflare’s SSL certificates rely on.
