Local network connection timeout on macOS Ventura

[RollinRolanding]

Details

I am running a simple Node server (on M2 Max Macbook 10.0.0.207, Node v18.16.1) listening on all interfaces but cannot connect to it from other devices (tried iPhone and another Macbook [10.0.0.78]). I can access the server on the machine it is running, 10.0.0.207. I have tried running a Python3 server listening on the same port (Uvicorn running on http://0.0.0.0:3000) and it is accessible from the iPhone and Macbook. I do not think it's related to my network, it seems related to Node and macOS

When the 10.0.0.78 devices attempts to connect I see the following in Wireshark:

On the machine running the server, the firewall allows node to accept incoming (I have tried turning the firewall off, it does not resolve the issue):

I have tried reinstalled node, it does not resolve the issue.

I have also tried different servers, like a Metro server, and the simple Node server below which logs the following on startup:

NODE_DEBUG=net node nodetest.js
NET 4254: setupListenHandle 0.0.0.0 3000 4 false undefined
NET 4254: setupListenHandle: create a handle
NET 4254: bind to 0.0.0.0
Server running at http://0.0.0.0:3000/

And lsof reports: node 4266 rolland 23u IPv4 0x6a8e48f63eab0429 0t0 TCP *:3000 (LISTEN)

Any help would be greatly appreciated.

can you substitute the ip for 0.0.0.0 and try once

I just tried on my macbookpro with some modification to print the incoming ip. worked fine for me

const http = require('http');

const server = http.createServer((req, res) => {
  const clientIp = req.connection.remoteAddress;
  console.log(`Received request from IP: ${clientIp}`);

  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello, World!');
});

const port = 3000;
const hostname = '0.0.0.0';

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

console log

@preveen-stack Yes I can! So changed 0.0.0.0 to 10.0.0.207:

NODE_DEBUG=net node nodetest.js
NET 2493: setupListenHandle 10.0.0.207 3000 4 false undefined
NET 2493: setupListenHandle: create a handle
NET 2493: bind to 10.0.0.207
Server running at http://10.0.0.207:3000/

Issue persists. Wireshark looks identical from what I can tell.

I also updated macOS Ventura to 13.4.1 to see if that might've been related, issue persists (Python3 connectable, firewall allows Node [even off, issue persists], etc.)

BTW my macbook pro is intel and not M1/M2
