I am unable to download any media using the Plex app for iOS. It just says “Unable to queue download.” I have tried restarting both my server and the phone and app, with no changes to the behavior.
I had been trying out Tailscale on my server PC and was using it with another program, but I think it may be causing this issue. I have since uninstalled the app from my PC and iPhone (and rebooted both), but cannot get the downloads to work.
To make matters even more frustrating, I share the server with a friend who has the same model iPhone, and he can download with no issues. And my iPad does just fine.
