Hostname SSL Problem... Need Help!

 Greetings,

I have tried several ways to have my server running the https// :2031  and it dont work

This site can’t be reached

uno.itronicpr.com’s server DNS address could not be found.

-------
That uno is a subdomain created using this instructions:
http://forum.centos-webpanel.com/ssl/ssl-for-cwp-itself/

And I have tried this:
http://wiki.centos-webpanel.com/hostname-ssl-with-letsencrypt

I have tried using the hostname, creating the subdomain and I never get it running. I really need your help. I have tried several ways and I always end reinstalling and starting from scrath using different ways to make it work.

I appreciate any help... Thank you

Make sure your sub domain need an A record point to your hostname server IP

I too am having difficulty, are using CWP.admin or CWP7.admin?

Thanks!
