#401 error for Plex watchlist sync
4 messages · Page 1 of 1 (latest)
I am running into the same thing today as well.
I've mentioned this in another thread but I had this issue a few months ago and it was because a user on my system had the movie 'Role play' in their watchlist. After removing that movie is all started working again.
I now have this issue again so it's either another movie causing it or something different. If you're the only user on your system try removing movies from the watchlist 1 by 1
A 401 is more likely than not a user who hasn't logged in a while and Overseerr cannot fetch their watchlist from Plex since the stored credentials have expired
