This certificate is not valid

This certificate and its chain is not valid, it signifies potential security and trust issues. An invalid SSL certificate could mean it has expired, been revoked, or not issued by a trusted Certificate Authority (CA). Additionally, an invalid certificate chain may indicate missing or misconfigured intermediate certificates, making it impossible to establish a secure connection to the website. In such cases, web browsers will typically display warnings to users, cautioning them about potential security risks, and it's advisable to avoid interacting with such websites to protect sensitive data from potential threats.
