Issues connecting to PMS

Assuming you’re not setting the server up for public access…

This is a new installation, correct? No play history, etc to save. So, just completely remove Plex and start over from scratch.

Per FAQ #9:

  1. Package Center - Remove the Plex package
  2. Control Panel → Users - Delete user Plex
  3. Control Panel → Shared Folders - Delete the Plex share
  4. Restart DSM

Then…

  1. Make sure the Synology and PC you’ll use for setup are on the same RFC 1918 IPv4 compliant network.
  2. Read Installation & Setup of Plex Media Server on Synology
  3. Download the latest public Plex Media Server release from plex.tv/download (the version available from Synology is a year old).
  4. Perform a manual installation per the Installation & Setup document.
