No DNS resolver could resolve the name.

DNS_DOMAIN_UNRESOLVABLE · Severity: Error

• ErrorDNS_DOMAIN_UNRESOLVABLE

  No DNS resolver could resolve the name.

  Every resolver we asked answered SERVFAIL or REFUSED for this name, so nothing under it could be checked and records shown as missing were not seen. The usual cause is a lame delegation: the registry still points to nameservers that no longer serve the zone. A broken DNSSEC chain gives the same answer. Mail servers and browsers that use these resolvers cannot resolve the name either.

  Recommendation: Check that the nameservers listed at the registrar serve the zone and that its DNSSEC records match. If the domain is no longer used, remove the delegation.
