Hostname related issue

I see some hostname related issues

In Change hostname I see

Your Hostname is: server.sslhosting.in and it resolves to IP: (ERROR: You don't have a valid hostname set!)
rDNS/PTR = FAILED, check with your hosting provider! FAILED

But server.sslhosting.in properly resolves to 173.249.22.198

Because of this, I see errors in BIND DNS status as well

Ex: Checking with google if domain is hosted on this server: FAILED

But websites are working.

Answered in other thread - don't double post!
