Pms won't launch and missing plist file

Server Version#:1.25.8
Player Version#:9.6.1.34323

i’m on mac os 12.5 and pms won’t launch at all
the plist file is missing from
~/Library/Preferences/com.plexapp.plexmediaserver.plist
i believe that might be the issue?
any advice on how to remedy?
thanks!

If the Plex Media Server won’t start and doesn’t even get to the stage where it’ll be writing to the server logs, 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.

thanks for assisting, this is what I get in terminal

Error: Unable to set up server: listen: Address already in use (N5boost10wrapexceptINS_6system12system_errorEEE)

There’s a few terminal apps / commands to identify what process is listening to a port (e.g. using lsof). If you’re confident only the Plex Media Server is using this, make sure to stop any stale instances and reboot your Mac before attempting to restart the server.

what am i looking for after running lsof?
how do i stop stale instances?
i don’t know much about this.
thanks!

You could use Activity Monitor to look for instances of Plex Media Server.
If you have a certain app you suspect of conflicting with another app you can also use Activity Monitor to see what files/ports that app accesses / listens to.

As for lsof you’ll probably need to google that. I know the options to use it have changed over time with different versions of macOS (or OS X before that). I’ve found some instructions but am not sure if they apply to macOS 12.5

Here’s the basic manual of the app → lsof Man Page - macOS - SS64.com
