DNS 5 REFUSED vs 17 BADKEY
Both DNS 5 (REFUSED) and 17 (BADKEY) belong to the DNS Response Codes (RCODEs) category. 5 indicates that query refused. The name server refuses to perform the requested operation for policy reasons. Meanwhile, 17 means that key not recognized. The TSIG key name in the message is not configured on the server.
Açıklama
Query refused. The name server refuses to perform the requested operation for policy reasons.
Gördüğünüzde
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.
Nasıl Düzeltilir
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.
Açıklama
Key not recognized. The TSIG key name in the message is not configured on the server.
Gördüğünüzde
Your TSIG-signed query or update references a key name that the server does not have in its keyring, so it cannot verify the signature.
Nasıl Düzeltilir
Ensure the TSIG key name matches exactly (case-sensitive) on both client and server. Add the missing key to the server's configuration if it is a new key.
