Simple application does not display



Hello, sometime ago i create some workspace and work fine. Today i became to work and try to run some code, but no luck.
In console:

Your code is running …
Example app listening on port 3000!

In browser:

ERR_CONNECTION_TIMED_OUT or No application seems to be running here!

Simple code:
var express = require(‘express’);
var app = express();

app.get('/', function (req, res) {
  res.send('Hello World!');

app.listen(3000, function () {
  console.log('Example app listening on port 3000!');


Try listening on port 8080 and IP adress instead. See also


Today all working fine.
