I am having this same issue. I reset my login settings also I could reset access to FordPass to add a new widget instance for my second Mach-E. Now the widget doesn’t work for either vehicle.

App worked for the last few days and now getting the same errors as kenyaw

Mine's worked for over a month just fine, but today it started giving me a different error. Then I tried to re-install the script and it's giving me this error now again. I'm assuming it's a problem on Ford's end.
Having the same issue here as well. Just started in last few days.
