Issues backing up since new auth

I got this message:

Failed to authorize using the OAuth service: The remote name could not be resolved: ‘’. If the problem persists, try generating a new authid token from: Duplicati OAuth Handler

Then I updated the auth token and got this message:

Unexpected difference in fileset version 8: 12/1/2018 5:00:00 AM (database id: 100), found 1527774 entries, but expected 1527775
