Use SSL/TLS Status or the certificate-management interfaces to inspect a domain's certificate.
Useful details include the covered hostname or names, issuer, certificate type, and expiration date. When troubleshooting, compare the hostname in the browser with the names covered by the certificate.
If a certificate appears valid in cPanel but a browser still shows a different certificate, verify that DNS points to the intended server and that the browser is reaching the same service you inspected.
