Hi guys,
Following the directions in https://forums.plex.tv/discussion/216845 I stopped the PMS service and set a different user in the following locations :
/etc/default/plexmediaserver
export PLEX_MEDIA_SERVER_USER=user/etc/systemd/system/plexmediaserver.service
User=user
Group=user
Then I rebooted the server as mentioned—app still won't load. What am I missing?
