- Are you both on the same subnet?
- 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
