How to Troubleshoot a cPanel Domain With a Certificate Name Mismatch

A certificate mismatch can occur when the requested hostname is not included, DNS points to another server, or a stale certificate is served.

Checks to make

Confirm the exact hostname and certificate names, check DNS and virtual-host mapping, inspect the active certificate and renewal status, and test the origin with the intended host header. Include aliases and subdomains where required.
