Nodejs address already in use :::5000

Question

I am trying to run a nodes app. I run node app.js. When I do, I get this error:

node:events:346
      throw er; // Unhandled 'error' event
      ^

Error: listen EADDRINUSE: address already in use :::5000
    at Server.setupListenHandle [as _listen2] (node:net:1311:16)
    at listenInCluster (node:net:1359:12)
    at Server.listen (node:net:1446:7)


Emitted 'error' event on Server instance at:
    at emitErrorNT (node:net:1338:8)
    at processTicksAndRejections (node:internal/process/task_queues:81:21) {
  code: 'EADDRINUSE',
  errno: -48,
  syscall: 'listen',
  address: '::',
  port: 5000
}

I spent hours looking at possible solutions online but none have worked so far. Same codebase works great on a different machine. This error happens on Mac M1 chip.

Does anybody have any idea how to fix this?

I tried finding processes running on 5000, I tried to kill them etc... nothing worked so far. I am running node 15.14.0.

I am on a M1 Chip, running macOS Monterey

How can I fix this error?

Answer 1

You should disable AirPlay on your mac. Because macOS Monterey started to listen to port 5000 and 8000.

System Preferences > Sharing > untick AirPlay Receiver

---

For macOS Ventura:

System Settings > General > disable Airplay Receiver

Answer 2

Lee Jeonghyun was correct. The reason why kill -9 PID would never work is because of this:

Control Center on Monterey is listening on 5000 as well.

I changed the port number in my nodejs app and the app started working again.
