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.
You've likely given it full control to whatever storage you've mounted in the container anyway, unless you've given it the :ro flag, which in that case would operate the same regardless of networking mode. If someone gains access to your internal host, you have bigger problems. Some things just play better under host mode and all bridged mode is doing is creating a virtual switch on your host and passing allowed traffic through it at a base level. The best way to protect is by running a load balancer in a DMZ and proxying all of the traffic through it which is how I have my instance running. I funnel everything external --> TCP\UDP 443 in DMZ vlan load balancer --> internal LAN IP:docker port. I run a mix of host network or bridged mode depending on the container.
