Enable SSL on centora panel

[betatester3.0]

I have VPS with ubuntu 14.04 installed. Port 443 is open and don't blocked by any firewall.

Hmm, use portchecktool.com and check if your ports are open. upload a screenshot when testing 443.

This is weird, have you set Sentora panel to port 443. Check the following Admin > Sentora Config look for "Sentora Apache Port" and see if that is set to port 80 or 443
