I tried testing a movie from my home server in plex through firefox and repeatedly got this message, even after reloading.
I knew that they had paywalled the apps on mobile and streaming from outside the network but now they have also blocked watching your own movies through your own hardware.
I do get the point that making software should be able to sustain people but I dont see the move of plex as a fair thing to do. Yes, they have made great software but taking your home server hostage feels like the wrong move.
Even a pop up that says "we need you to donate please" would have been fine. make it pop up before every movie, play donation ads before any movie but straight up disabling the app is kinda cruel.
Anyway, i have switched to jellyfin and it is insanely good. please give it a try. you can run it alongside plex with not issues (at least i had none) and compare the two.
In any case, good luck. Let me know if you need help.
Ahh OK, a Docker bind. 3 things to check:
That you added the folders in that weird way Unraod requires, see: https://forum.jellyfin.org/t-solved-jellyfin-not-detecting-media-in-unraid (this probably isn't it, but worth checking)
Make sure for newly added, Jellyfin is configured for Date File Scanned into Library, vs the Created Date on the file
Ensure the Arrs aren't set to change the date on file import. By default they modify created/modified dates to be the release date, which can put things in an unexpected order.
