404 Not Found

Server Version#: 1.28.1.6104-788f82488
Player Version#:

Very new to Plex. Tried downloading it to my new desktop Mac. Latest software (OS Monterey 12.5.1). Installed Plex app no problem, but Plex Media Server does not seem to work. When I click on it it takes me to a web page that simply says “404 Not Found”. I get no further information. Help?

If the Plex Media Server won’t start or doesn’t give you any output, you can attempt the following procedure to see if there’s any error messages on the OS level:

  1. Open Finder and navigate to /Applications
  2. Select Show Content from the context menu of the Plex Media Server.app item
  3. Navigate to Contents/MacOS
  4. Open the Terminal app
  5. Drag the Plex Media Server executable from the Finder window (#3) into the Terminal Window and press Return to execute it

This is no different from running the app, so it won’t succeed – but you should get a more specific error message about what’s causing it to fail starting.

Beyond that it might be worth to take a look at the server logs (you can access those directly in your file system if you cannot access them through the Plex web app).
