Why domain SSL checks matter

A valid certificate helps protect users, improves trust, and supports secure browsing, transactions, and account access.

When to run a domain SSL check

Run this check before launches, after SSL installation, after domain or server changes, or when investigating security warnings.

How to interpret the result

The main checks are validity, expiry, certificate-to-domain match, and whether the domain serves a trusted certificate chain.

Common domain SSL problems

Frequent problems include expired certificates, wrong hostnames, incomplete chains, and serving certificates from the wrong virtual host.
