Step 1: Check the Server

  • Is it powered on?
  • Can you access it locally via its hosted URL, http://localhost:32400/web or its IP address?

Step 2: Internet and Networking

  • Make sure your server is online
  • Check your router for changes to port forwarding (especially for remote users)

Step 3: Plex Media Server Updates

  • Check for updates — both the server and your Plex apps
  • Outdated versions often cause weird issues

Step 4: Scan and Repair Your Library

  • Missing media? Try Update Library or Refresh All Metadata
  • Use “Analyze” or “Optimize” features for better performance

Step 5: Logs Are Your Friend

  • Find them in the Plex Web App under Settings > Troubleshooting > Download Logs
  • Or locate them manually in the Plex Media Server data folder

When in doubt… restart everything. Plex. The router. The server machine. Nine times out of ten, that works.
