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.
That's basically what I do right now except I do have a domain and my ISP doesn't restrict inbound ports like 443 so it works fine.
Just trying to sort out if I want the headache of a VPS if I don't need it (costs, maintenance, point of failure, etc).
Sounds like you don't need the VPS then. Add a subdomain to your home IP. Port forward 443 and 80 to the sever. Run caddy to route the subdomain to localhost:8096. You will also need to tell jellyfin to accept on the new domain.
