openssl s_client -connect your-host:443 If it says something like gethostbyname failure then try following. It needs socat, which can be installed on macOs like this — brew install socat. Then in one terminal open socat TCP4-LISTEN:10443,fork TCP6:your-host:443 and in another terminal: openssl s_client -crlf -connect 127.0.0.1:10443
