I've had a working installation of Overseerr (latest version) for a while now, but recently I'm stuck in a login loop. When I try to login, either using Plex auth or local user auth, I click on "sign-in" and it just hangs. If I restart the container, sometimes I can get in for a short while (under a minute) but then it kicks me out. But I don't seem to be able to do that anymore now.
I know that the login auth gets to Plex because I (sometimes) get the email from Plex saying "New sign-in to your Plex account". But for whatever reason I can't get in.
Some of my 5 external users can get in okay, But some have also intermittently experienced this problem.
It happens whether I'm going via NPM or directly at host:5055
I've tried the obvious - different clients, different browsers, different machines etc. No change.
Nothing in the logs of any note.
Anyone experienced this? Anyone got a fix? Anywhere else I can look for more descriptive logs?
