Plex in Docker and the problem of always appearing as "Remote"

Since putting plex into a docker container, I have been noticing that when I attempt to play media through the Plex application on my apple tv, it will default to transcoding down to a lower quality. I can always manually set the quality back to original quality but its clearly not ideal because the remote path is bandwidth limited.

This is what I've observed when connected to Plex using a web browser:

  • https://app.plex.tv/desktop/ --> server shows as "remote" and i'm bandwidth limited
  • <NAS IP ADDRESS: PORT> --> server shows as "nearby" and is therefore recognised as being on the internal network
  • <synology.me address routed through synology reverse proxy pointing to plex> --> server shows as "nearby" and is therefore recognised as being on the internal network

What I've tried:

  • added the reverse proxy url to the ADVERTISE_IP environment variable in the docker container --> no change
  • added the relevant IP's to the ALLOWED_NETWORKS environment variable in the docker container. Eg: I set mine to “192.168.0.1/24,172.17.0.0/12” to include my local network subnet and the network space that docker runs in.
  • Following the advice outlined here--> no change

Any ideas?
