Check If Your Domain Is Expired Or Still Active
Also check the DNS on your web server that all settings are correct
Or maybe the DNS server is down
Contact your domain registrar! If this problem cannot be fixed! Most likely they can help you

If you check my OP I did all of that - no need to contact the domain registrar.  Also if you check my OP it's working now.  It was temporarily not working.  Domain is with Namecheap and expires only next year in February.  Name servers were created with Namecheap.  Checked the DNS and everything was OK.  But yes - who knows, maybe the DNS server was down temporarily.
