Why check certificate expiry?

An expired certificate can trigger browser warnings and disrupt secure connections. Set a reminder before expiry and renew through your hosting provider or certificate authority. Use our website hosting lookup to find hosting details.

This quick check reads the certificate from a public hostname. It does not validate the complete browser trust chain.
