Google Cloud Compute Engine-Node.js无法正常工作

Question

I created a free server from Google Cloud. I want to run Node.js on this server. I installed Node.js. I installed Express and created a project. Then I run the project (working).

But I can not get the output by typing ip-address: 3000. "This site can not be reached." I get as a result.

What could be the reason for that.

Answer 1

I just setup one to see how this works, how i setup the server, hope this helps:

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

app.get('/', (req, res) => {
    res.json('Home Page');
})

app.listen(8080);

The web applications must listen for HTTP requests on ports within the permitted range 8080 to 8084.....To connect to a web application running on an instance, click the Web Preview button Web Preview Button above the Cloud Shell terminal window in the GCP Console. src: https://cloud.google.com/shell/docs/features#web_preview
