Hi @salas81, welcome to the GitHub Support Community! It definitely sounds like it might be a certificate problem on your machine, or it could be as something simple as the date and time.
First, can you please check in
System Preferences /
Date & Time that the time and date are set correctly on your computer?
Then, if that is okay, on the error page, please click
Advanced and copy/paste the error message.
Next, please click the
⚠️ Not Secure in your address bar and take a screenshot (
Cmd-Shift-4) of the certificate chain (or let me know any errors you see on that screen).
Also, could you please verify which version of macOS you are running (Apple menu /
About This Mac) and which version of Chrome you are running (
chrome://version in your address bar)?
The next step would be to check the CA certificates in
Keychain Access, based on any errors there. The necessary root CA certificate is
DigiCert High Assurance EV Root CA.
P.S. - This is not a fix, but a short term workaround… you could use Firefox while you are troubleshooting this, as it uses its own certificate store instead of the system Keychain.
