Looks like you're trying to add gamepaduniverse.info to your server. Doing a nslookup shows gamepaduniverse.info pointing to 50.63.202.25, and looking up the DNS records, the name server shows it hosted on domaincontrol.com. To correct this, log into your domain parker and update the NS record to match the correct NS record of your server (which looks to be ns1.gamepaduniverse.com and ns2.gamepaduniverse.com) and that warning will go away when the DNS propagate.
