DNS_ERROR_RCODE_BADTIME

DNS_ERROR_RCODE_BADTIME means the signature validity time on the DNS request was unacceptable. Clock skew, a stale signed request, or a signing-window mismatch can cause it.

What to check

Verify time synchronization on the DNS server and on the system submitting the signed request.
Check whether the request was delayed or replayed beyond the configured signing tolerance.
After correcting time and key state, generate a new request instead of replaying the failed message.
