ERR_SSL_VERSION_OR_CIPHER

This error is usually caused in older browsers that do nto support the latest TLS Ciphers. However it can also occur in modern browsers if the server is not correcty configured.

The first possibility is that the domain name on the certificate does not match the domain name being entered into the browser. Either your server is routing the request to teh wrong domain or the certificate has the incorrect domain name.

The other possibility is that the cipher suites on the server have ciphers enabled that are either no longer supported or considered insecure.

Take a look at the SSL Labs website. If you run a test against your server it should highlight if the name is incorrect or if there are unsuported cipher suites enabled on the website.
