Answer

To test if your website's SSL certificate is valid, you can use online SSL checker tools or command-line utilities like OpenSSL to verify the certificate's details, including its expiration date and chain of trust.


    openssl s_client -connect yourdomain.com:443 -servername yourdomain.com

Additional Comment:

Use the command above in a terminal to connect to your website and retrieve SSL certificate details.
Look for the "Verify return code: 0 (ok)" line, which indicates a valid certificate.
Check the "Certificate chain" section to ensure all intermediate certificates are correctly installed.
Online SSL checkers like SSL Labs can provide a detailed analysis of your SSL setup.
Ensure your certificate is not expired and matches the domain name.
