TLS certificates have defined validity periods. If a certificate expires and is not renewed or replaced, browsers may display security warnings when visitors access your website.
An SSL checker can help confirm whether a server presents a certificate for the requested hostname.
A certificate must cover the hostname visitors use to access your website. If the certificate does not include the requested domain, browsers may report a certificate name mismatch.
Certificate information can identify the issuing certificate authority and help you verify that the certificate matches your intended deployment.
