I’m running plex server in docker on a headless server, using the this simple docker-compose.yml:
version: '3'
services:
plex:
image: plexinc/pms-docker
volumes:
- plex-database:/config
- plex-transcode:/transcode
- /media/store:/data
environment:
- TZ="Aemrica/Toronto"
- PLEX_UID=975
- PLEX_GID=975
network_mode: host
volumes:
plex-database:
plex-transcode:
Everything works fine except that the server can’t transcode videos using h264 codec. Here is the part of log that I think relevant.

Apparently it tried to get the codec from downloads.plex.tv but failed due to request time out. It looks like the network is not properly setup but plex can retrieve meta data like fan arts from the web. The full log is attached.
