M-PNAU6 -E- [domain] NS at AAAA not responding, not authoritative, or wrong serial: ns

THE PROBLEM EXPLANATION:

The cause of the error is related to the IPv6 AAAA record. The zone file contains a NS record with an AAAA record, but the specified IPv6 address does not provide the same SOA record for the domain.

SOLUTION OF THIS PROBLEM:

Also configure the name server at IPv6 address.
