If the server responds by IP address but the domain name does not reach it, focus on DNS and virtual-host mapping rather than application code.
- Confirm the domain is registered and delegated to the intended authoritative nameservers.
- In the authoritative DNS zone, verify the root and relevant hostnames have the intended A/AAAA/CNAME records.
- Compare public DNS results with the values in cPanel Zone Editor.
- If cPanel is not authoritative for the domain, edit DNS at the service that actually hosts the authoritative zone.
- Allow existing cached records to expire according to their TTL after a change.
Changing a record in cPanel has no public effect when another DNS provider is authoritative for the domain.
