Error code 400 trying to sign in to Zoom add-on in Google Calendar

[jgelis57]

I am trying to sign in to a newly installed Zoom add-on to Google Calendar.  It was obtained from the Google Marketplace. My login credentials are identical between Zoom and my new Google business account. I repeatedly receive an extremely long URL and then the dreaded 400 error. At a lost. Help anyone.
