Why does it say certificate expired?

When a certificate expires, it means its validity period has ended, causing it to become untrustworthy and non-functional for its original purpose, like securing websites (HTTPS) or digitally signing documents, leading to browser warnings, connection failures, loss of encryption, and potential security risks like data interception. Browsers and systems stop recognizing it as valid, effectively blocking access or flagging it as unsafe until renewed or replaced.

How do I fix an expired certificate?

To fix an expired certificate (usually SSL for websites), you need to renew it by generating a new Certificate Signing Request (CSR), submitting it to your Certificate Authority (CA) for validation, and then installing the newly issued certificate on your server, often via your hosting control panel like cPanel or by running commands like certbot renew, followed by restarting your web server. The exact steps depend on where you got the certificate, but the core process involves getting a new one and deploying it.
