Hello all,Firstly, I'm a bit of a beginner so please be as patient as you can.I set up a practice website that sent data collected from a form to a database. It worked.I then tried to install an SSL certificate for better security. Unfortunately it didn't work (when typing URL my browser couldn't open the page). I then discovered certbot and used this to attempt to install an SSL certificate. It doesn't work now. As I didn't make the changes myself I can't go back and undo them. To be specific, when I type my domain into the browser it shows me this (in Chrome):"This site can't provide a secure connection" and "ERR_SSL_PROTOCOL_ERROR".Would somebody be willing to help?So far I have this from openssl (sorry if it formats terribly, like I said; beginner):james@localhost:~$ openssl s_client -connect www.mydomain.com:443CONNECTED(00000003)140444419827352:error:140770FC:SSL routines:SSL23_GET_SERVER_ HELLO:unknown protocol:s23_clnt.c:794: ---no peer certificate available---No client certificate CA names sent---SSL handshake has read 7 bytes and written 305 bytes---New, (NONE), Cipher is (NONE)Secure Renegotiation IS NOT supportedCompression: NONEExpansion: NONENo ALPN negotiatedSSL-Session:Protocol : TLSv1.2Cipher : 0000Session-ID:Session-ID-ctx:Master-Key:Key-Arg : NonePSK identity: NonePSK identity hint: NoneSRP username: NoneStart Time: 1495028612Timeout : 300 (sec)Verify return code: 0 (ok)I'm running Ubuntu 16.04 and Apache 2.4.18 (Ubuntu).If anybody could help me I would really appreciate it. I only did the SSL stuff this morning and I have heard it could take up to 24 hours to work, but still...Thanks,JamesPS: If there is a more suitable list I can contact, please let me know.
