FAQ 25: Reclaiming a lost server

This How-To is better than the :exploding_head: nuclear option of starting over.

DSM 7

To reclaim a “lost” server. (lost / locked out / password reset)

  1. Uninstall the package with the “KEEP” option.
  2. Reinstall the same package again, selecting the “Plex Claim Token” option
  1. Click NEXT, NEXT, and DONE to continue installing.

  2. After about 15 extra seconds, The installer will confirm you’ve installed the package again AND whether or not it is reattached. When reattached, it will show your Plex username.

  3. Open a private browsing window to the LAN IP of the Syno ( http://lan.ip.of.syno:32400/web )

  4. Sign in, ignore the “Not Hosted by Plex” warning. Confirm everything is back.

  5. Close this window and reopen normally. Claiming is complete.

DSM 6

This is written this for worst case (reclaiming may happen 2 ways - both are shown here). It will likely only need through step 16 but I’ve provided everything just in case.

  1. Install the Synology Text Editor app (in Package Center - Search)
  2. Stop Plex
  3. In your web browser, https://app.plex.tv
  4. Settings - Authorized Devices - Servers (drop down)
  5. Remove the Synology (we will make it appear again in a minute)
  6. Sign out of Plex/web (upper right corner)
  7. Open File Station
  8. Plex share / Library / Application Support / Plex Media Server
  9. Right - click “Preferences.xml” → Open in Text editor.
  10. Very carefully, remove the complete Name="Value" pairs,
    a. PlexOnlineToken="-value-"
    b. PlexOnlineUsername="-value-"
    c. PlexOnlineMail="-value-"
    d. PlexOnlineHome="value"
  11. Save the file.
  12. Right-click Preferences.xml again and make certain it is still owned by plex
  13. Start Plex
  14. Back in your browser - Open an Incognito window
  15. Open http://ip.addr.of.syno:32400/web
  16. It will ask you to sign in again
  • In case it thinks “We’ve found a new server”, continue with step 17 below.
  1. Expect the “Got It” message and “We Found a new server”.
  2. The setup wizard is also likely to start. We will SKIP through this.
  3. Do not create any new library sections. All your existing media still is there.
  4. Continue forward until you FINISH and get to the dashboard.
  5. You’re done.
