Error: listen EADDRINUSE: address in use

This means the port SnailyCAD requires is already in-use. This should be a simple fix.

Example Error

Error: listen EADDRINUSE: address already in use
at Server.setupListenHandle [as _listen2] (node:net:1372:16)
at listenInCluster (node:net:1420:12)
at doListen (node:net:1559:7)
at processTicksAndRejections (node:internal/process/task_queues:84:21) {
errno: -4091,
syscall: 'listen',
address: '',
port: 3000

Possible ways to fix it

  • Verify there are no other programs/processes running on this port.
  • Restart your VPS/PC
  • Kill the process via: npx kill-port <port-here>
