title: This site can’t be reached on Nodejs Express?
body: <p>I'm totally new to Node and I tried to run a test site on a hosting centos 7 (vultr.com). I've got nodejs, express installed.</p>
  
  <p>Hello.js</p>
  
  <pre><code>const express = require('express')
  const app = express()
  
  app.get('/', function (req, res) {
    res.send('Hello World!')
  })
  
  app.listen(3000, function () {
    console.log('Example app listening on port 3000!')
  })
  </code></pre>
  
  <p>run node hello.js</p>
  
  <p>On my PC, <a href="http://x.x.x.x:3000/" rel="nofollow noreferrer">http://x.x.x.x:3000/</a>  => shows This site can’t be reached</p>
  
  <p>x.x.x.x took too long to respond.</p>
