जब आप इसे देखें
The domain has no DNS records at all — either it was never registered, has expired, or you have a typo in the hostname.
कैसे ठीक करें
Double-check the domain spelling. If you own the domain, verify your registrar settings and ensure the nameservers are correctly delegated.
विवरण
Key not recognized. The TSIG key name in the message is not configured on the server.
जब आप इसे देखें
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.
कैसे ठीक करें
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.
