3 NXDOMAIN

Non-Existent Domain. The queried domain name does not exist in the DNS namespace.

Khi bạn thấy mã này

The domain has no DNS records at all — either it was never registered, has expired, or you have a typo in the hostname.

Cách khắc phục

Double-check the domain spelling. If you own the domain, verify your registrar settings and ensure the nameservers are correctly delegated.
