I suspect you’re impacted by us trying to verify your nameservers. From a dig I see arch & rihana, but whois shows:

      NS1.BYET.ORG
      NS3.BYET.ORG
      NS4.BYET.ORG
      NS2.BYET.ORG
      NS5.BYET.ORG

We need valid nameservers in order to validate the name, was this site ever active with an indication of “nameservers confirmed” before you removed it? You may need to change the nameservers at your registrar to something we can verify.
