Since you've got an invalid certificate error, I'll make the following suggestion based on my personal security practice.

If you're still in your servicing terms with your CA, ask them to issue a new valid certificate for you.

Check your Keychain setting and make sure no CA cert is missing.

Alternatively, you can issue your own self-signed certificate for testing purposes, and add it to your local Keychain as trust anchor. A search for "how to create self-signed x509 certificate" will return something you might find useful.
