8 NXRRSET
RR Set that should exist does not. A required resource record set is missing from the zone.
متى ترى هذا الكود
A DNS UPDATE prerequisite expected a certain RRset to exist (e.g., an MX record), but the zone does not contain it.
كيفية الإصلاح
Create the missing RRset in the zone before retrying the update, or change the prerequisite to not require its existence.
