[BlackStar7713]

Windows Version

Microsoft Windows [Version 10.0.22631.3737]

WSL Version

WSL version: 2.2.4.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

Linux version 5.15.153.1-microsoft-standard-WSL2

Distro Version

Ubuntu 22.04

Other Software

nodejs v20.15.0

Repro Steps

I have an issue connecting to a server, and during debugging I created this minimal example:
Follow instructions in https://learn.microsoft.com/en-us/windows/wsl/networking under Accessing Windows networking apps from Linux (host IP).
I created a simple nodejs server like follows;

const http = require('http');

// Define the port to listen on
const port = 5000;

// Create an HTTP server
const server = http.createServer((req, res) => {
  console.log('Received an HTTP request.');

  // Send a response
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello, world!\n');
});

// Make the server listen on the specified port
server.listen(port, () => {
  console.log(`Server running at http://localhost:${port}/`);
});

When using curl http://127.0.0.1:5000 I get the expected response, and output in the server console
On WSL i checked /etc/resolv.conf for the nameserver ip (10.255.255.254 in my case) and called curl http://10.255.255.254:5000

Expected Behavior

I expect the response Hello World and a http request to be received by the server

Actual Behavior

The command fails:
curl: (7) Failed to connect to 10.255.255.254 port 5000 after 0 ms: Connection refused

Hi, @BlackStar7713 can you try following steps and check if its work:

Step 1: Getting IP address of windows machine using following command.
ip route show | grep -i default | awk '{ print $3}'

Step 2: Try curl with the IP address you got in step 1 and port with your given port.

Hi @osamakhanedu
the iproute command gave me 172.24.32.1 as an ip.
When using curl with it it times out:
curl: (28) Failed to connect to 172.24.32.1 port 5000 after 129745 ms: Connection timed out
I tried to attach a new log file but the zip is 45MB, more than GitHub allows. I'll try to put it on a file share and edit in a link soon
