Also, let’s look at the Plex logs. See if they show anything.

  1. Make sure your server is set for debug level logs.
    Settings → Server_Name → General
    Check the box for debug logs.
    Do not check the box for verbose logs.
    Save Changes if needed.

  2. Plex Dance the movie (so the logs will capture adding it to the system).

  3. Wait for Plex to finish re-scanning the movie, downloading metadata, etc.
    Pull the log files: Settings → Troubleshooting → Download Logs.
    Attach the ZIP file to the thread.
