Hi Mike,
As far as I’m aware you haven’t been doing any work/upgrading on the server lately, but figured I’d still report here in case anyone is experiencing the same.
The past approx 5 weeks has seen me getting the attached error with increased frequency when logging in or out, or both. There doesn’t seem to be a consistent pattern of time of day, work or home, or wifi or not. But sometimes it’s been taking quite a few tries to log in. (It doesn’t bother me, really, when logging out.)
