Quand vous le voyez
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.

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.
