I did not post any screenshots. You will be prompted during the installation process.
- Uninstall Plex Media Server using the “Sign out and unclaim” or the “Uninstall Only” option.
- Perform a manual installation in Synology Package Center (do not install the beta version).
- Select the “Plex Claim Token” option when re-installing.
- Click “Get Plex Claim Token”.
- Browser tab will open and display a “claim-xxxxxxx” token string
- “COPY” the string
- Return to the installer window
- PASTE the
claim-xxxxx
into the small window on the form. - Click NEXT until it starts installing.
- Installation will need an extra 15-20 seconds for the installer to communicate with Plex.tv and obtain new credentials for your server. After it receives the credentials, it updates your “Preferences.xml” automatically so the server is again connected to your account.
- The installer will confirm success or failure attaching. Success will include your Plex account username in the message
- Open an Incognito Browser Window.
- Connect http://LAN.IP.of.Syno:32400/web
- Confirm Sign in
