    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. 5611.ns1.abovedomains.com, 5611.ns2.abovedomains.com, ns1.abovedomains.com, ns2.abovedomains.com report NS ns1.abovedomains.com ns2.abovedomains.com. Only at the parent: 5611.ns1.abovedomains.com, 5611.ns2.abovedomains.com; only in the zone: ns1.abovedomains.com, ns2.abovedomains.com.
