このコードが表示された場合
You sent a dynamic update or zone operation to a server that is not the authoritative master for that zone, or the server rejected it due to TSIG authentication failure.
修正方法
Send the update to the correct primary authoritative server for the zone. If using TSIG, verify the key name and secret match on both client and server.
