Why No name servers found at child

domain-name-system

No name servers found at child.

  1. Superfluous name server listed at parent: ns3.soonce.com
  2. Superfluous name server listed at parent: ns4.soonce.com

Why am I getting this error here?

But not here?

Running a cPanel server on ns3 + cPanel DNS Only on ns4. What does it really mean and how do I solve it?

NS3 does not respond to queries for itself and the other name server:

$ dig @83.169.20.193 ns4.soonce.com

NS4 responds correctly:

NS4 is also not returning glue records. There should be an ADDITIONAL SECTION with the A records for the two name servers after the ANSWER SECTION:

$ dig @83.169.20.193 soonce.com NS
