The Google sign-in expired or was already used
Why it happens
Each sign-in has one link, valid for ten minutes, used once, and only in the organization that started it. This one expired, was already used, or belongs to another organization.
What to do
Go back to the email settings, choose “Connect Gmail” again, and finish signing in within a few minutes.
