[FIXED] Why i don't see response when I type in browser IP and port where nodejs is listening?

Issue

I'm trying to understand how nodejs server works and how to get NodeJs server to send an Html when I send a request to do it.

I have a nodejs with express in a VPS. In the same VPS i host a webpage through vesta. I have a code to listen in one port (4000) and I want it to send an Html. when I run the node file I have the feedback that server is listening, but when I type the IP of the webpage and the port in my browser (IP:4000) I get This site can’t be reached.

I'm not using port 8080 because that port is already in use by HTTP and I get the error listen EADDRINUSE :::8080

What am I missing?

const express = require('express');

const app = express();

const PORT = 4000;

app.get('/about', (req, res) => {
  res.sendFile('./views/page.html', { root: __dirname });
});

app.listen(PORT, () => {
  console.log(`Server running at: http://localhost:${PORT}/`);
});

Solution

Make sure that your VPS is listening to port 4000.
