You should not support the SSL protocol at all. You should also not support TLS 1.0 or TLS 1.1. Therefore, your configuration should only support TLS 1.2 and up. Some server versions may not support TLS 1.3 yet, therefore TLS 1.2 must be the cornerstone of your configuration. This protocol version is supported by all current browser versions and quite a few outdated versions, therefore, you should not run across compatibility problems.
