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 access my stuff via VPN. As for sharing with others, I simply don't do that. VPN is still an option though. Or temporary client whitelisting, etc.
Now that's an interesting thought.
A web page with Authelia, login and a firewall.
If you're not logged in, All you get is a login page. If you are logged in, It passes you straight through to jellyfin.
So any device and client would be able to access it without issue once a phone or computer on the network had logged in just once.
The web page modifies the HA proxy ACL and forces a reload.
