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.
I just wonder if plex will ever sell the list of movies and IP address of everyone. Many people have the ARRs to auto download, even stuff still in theaters. What good is a VPN when plex knows your email and IP.
Honestly, I'd be rather shocked if this wasn't already the case.
Moreover they probably have a database of everything you've ever watched and your IP and email address, just waiting to be leaked to the internet through sale or ransom.
Sell or get subpoena'd; tomayto, tomahto.
