ECONNREFUSED on NodeJS 18

When using node-fetch on NodeJS 18, got ECONNREFUSED

// test.mjs
import { Server } from '@hapi/hapi'
import fetch from 'node-fetch'

const start = async () => {
  const server = new Server({
    port: 3344,
  })

  server.route([
    {
      method: 'GET',
      path: '/',
      handler: async () => {
        return JSON.stringify({ value: 'hello' })
      }
    }
  ])
  await server.start()


  const response = await fetch('http://localhost:3344')
  console.log('response', await response.text())
}

start()

Steps to reproduce the behavior:

1. Run the above in Node 18.7.0. It fails with:

FetchError: request to http://localhost:3344/ failed, reason: connect ECONNREFUSED ::1:3344
    at ClientRequest.<anonymous> (file:///D:/code/mocktomata/node_modules/node-fetch/src/index.js:108:11)
    at ClientRequest.emit (node:events:513:28)
    at Socket.socketErrorListener (node:_http_client:481:9)
    at Socket.emit (node:events:513:28)
    at emitErrorNT (node:internal/streams/destroy:151:8)
    at emitErrorCloseNT (node:internal/streams/destroy:116:3)
    at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
  type: 'system',
  errno: 'ECONNREFUSED',
  code: 'ECONNREFUSED',
  erroredSysCall: 'connect'
}

Expected behavior

The same script will work in NodeJS 16.

I started seeing this and the only solution I found was to use the IP 127.0.0.1 instead of localhost. I’m not sure why

Can confirm this issue on Node version v18.8.0. I am getting the very same error on different port 8080. Calling with curl works, calling from node results in ECONNREFUSED as described above.

I can also confirm that the very same code works on node v16.17.0. I can also confirm that changing localhost to 127.0.0.1 fixes the issue.

OS: NixOS, Linux. Node-fetch: 2.6.7
