Plex Media Server NAS & Devices

Thanks for the screenshot. If things were working correctly, you should see your server listed below the Plex Web setting.

A few questions and please pull the log files.

  1. Look in your list of Authorized Devices. Is the server listed?
    https://app.plex.tv/desktop/#!/settings/devices/pms

  2. If so, is it running?
    In Synology Package Center, click on the Plex icon (not “open”).
    Is the status “Running”?

  3. Do you have a PlexMediaServer shared folder?
    Synology Control Panel → Shared Folder
    If this is not present, then the installation failed for some reason.

  4. Please manually retrieve the log files.
    a) Stop Plex Media Server
    b) In Synology File Station, navigate to PlexMediaServer/AppData/Plex Media Server.
    c) Right click on the Logs directory and choose Compress to Logs.zip.
    d) Download the zip file (right click → Download).
    e) Attach to this thread. Drag it into the message window, it will insert at the cursor location.
