1.What does 'Server Error. certificate has expired' mean?
2. How can I fix it?

~~~~EDIT~~~~

• I erased my hard drive and installed a fresh operating system; still not working.
• Opened an issue on the angular/angularfire git page: https://github.com/angular/angularfire/issues/2285
• Found that the angular/fire package.JSON uses firebase tools 6.10.0 when firebase tools is up to 7.12.1 tried to fix by forcing the project to resolve a newer version of firebase-tools using resolutions in package.json with yarn at the suggestion of @wSedlacek on GitHub. Didn't work.
• I changed the system time to before this issue started happening and it now works, issue still not fixed because it is a minor inconvenience to roll system time back to January 4th, 2020 every time you want to start a project.
• @wSedlacek found that an HTTPS cert is expiring the due to the older version of firebase-tools in the package.json had a cert that expired on either January 5th 2020.

This issue might be related since it started happening at the same time : Why is angular fire saying I'm not logged in even though firebase tools says I am?

Here is a picture of the error:
