Your DNS is fine, and like you said, pinging your server using either its IP address or either of those hostnames works fine.
So you appear to have either:
a) an ISP issue, where your ISP is blocking ports
b) a firewall on your server, which is blocking ports
c) Sentora is not installed correctly
The only port that seems to be open and accessible is port 22 for SSH. ALL ports that Sentora uses (e.g. 80 for http, 25 for SMTP, etc.) are not answering. Pinging is not necessarily port-based, and the OS will answer pings right from install, so that shows nothing about whether Sentora is running correctly or not.
If you truly installed onto a vanilla, brand-new CentOS 7 server then you shouldn't have a firewall blocking all those ports by default - unless there's some variant of CentOS 7 that I haven't heard about. So I'd go with either your ISP blocks everything (which I doubt), or Sentora just isn't installed properly.
Run this command, make sure you have shown all lines, then copy/paste the output to show us which services are running:
Then at least we can begin to see if you installed Sentora and what is running on your server.
