Summary

This error message is critical because it reveals that your current server fails the SSL validation requirements, preventing users from accessing your site safely. The specific details in your text indicate that the server certificate presented to visitors is outdated or improperly signed by the Certificate Authority. Such vulnerabilities could compromise the integrity of user data and expose them to man-in-the-middle attacks if not addressed immediately.

Contact your hosting provider to request a certificate renewal that explicitly validates against your domain, ensuring it is issued by a trusted Authority and matches your current SSL configuration. Replacing this old certificate with a new one verified by a reputable CA will prevent these critical security gaps and guarantee that all traffic is trusted.
