node app not visible in browser aws ec2

    var express = require('express');
var app = express();

app.listen(3000, ()=>  {
    console.log('listening');
});

app.get('/',(req,res)=>  {
    res.send('hi');
});

Here is what the above code is Doing:
1. We’re requiring the express module.
2. We’re creating an express app.
3. We’re telling the app to listen on port 3000.
4. We’re telling the app to respond to a GET request to the root URL (‘/’) with the text ‘hi’.
5. We’re telling the app to respond to a GET request to the /bye URL with the text ‘goodbye’.
6. We’re telling the app to respond to a GET request to any other URL with the text ‘page not found’.
