Plex for Synology - No 'Plex' Folder shown in DSM

Hi, i have re-started using plex on my Synology box. Have gone to add a channel and there isn’t a plex folder or share on my Synology NAS (I may have deleted it previously when i wasn’t using Plex).
I also get an error “The channel directory is unavailable.” when I try to add a channel (home > channels > install channels) via a browser window.
Also, going settings > server gives a “Server settings are unavailable.” message.

Is it simple to re-add the folder (if that indeed is the issue) or maybe a fresh install of Plex is in order?

By default, the Plex share is hidden from File Station (Synology’s rules)

Go to Control Panel - Shared Folders
Edit the Plex share.
Add your username as R/W permission
Save the changes

If Server settings are unavailable, PMS is not recognizing you as the owner.

  1. Are you both on the same subnet?
  2. Is it and your browser both signed in as the same Plex.tv account ?

Adding a plug-in is easy to put into position however, PMS does not run as a privileged user on Synology.
After putting the files into position, you must SSH into the Synology as admin, sudo -su root to elevate to root privileges, and assign user plex as the owner of the files in those plug-in(s).

Presuming your Plex share is on /volume1 (default), you can use the following. If on another volume, please adjust accordingly.

chown -R plex:users "/volume1/ Plex/Library/Application Support/Plex Media Server/Plug-ins"

Restart PMS and it will now find the plug-ins

This worked for me as well. I wonder if this should be made the default for users moving from other platforms to Synology.
