DNS
5 REFUSED
Query refused. The name server refuses to perform the requested operation for policy reasons.
When You See This Code
The server rejected your query due to access control — for example, a recursive resolver that only serves its own network, or a zone transfer blocked by ACL.
How to Fix
Check the server's allow-query, allow-recursion, or allow-transfer ACLs. If you are not authorized to use this resolver, switch to a public DNS service.
