Omnipresence not working on Catalina

The app isn’t syncing, it can’t find the server.
Tried deleting and reinstalling.
Tried removing omnipresence folders from Library/containers

Using omnipresence 1.6
Using catalina latest

Ahh, I had to give the app Full Disk Access in Security in System Preferences.

Argghh and then got the exclamation point again after one sync.
