Some common errors in using SSL certificates are:
Expiration date passed: The SSL certificate must be regularly renewed, if the expiration date has passed, the certificate can no longer be recognized as valid.
Incomplete configuration: SSL certificates must be correctly configured on the web server to ensure they work properly.
Untrusted certification authority: It's important to obtain a certificate from a trusted certification authority, as this can otherwise question the integrity of the certificate.
Mismatch with domain name: The SSL certificate must be issued for the correct domain name to ensure it's being used on the correct website.
Failure to update certificate after a change in domain name: If the domain name changes, the SSL certificate must also be updated to ensure it remains valid.
