title: Node.js on Google Compute Engine
body: <p>I have established ssh connection. Following that, I have run my node.js application by node app.js on port 3000. It showed console output app is running <a href="http://0.0.0.0:3000" rel="nofollow noreferrer">http://0.0.0.0:3000</a> port same as my local environment. But when I opened <a href="http://external_ip:3000" rel="nofollow noreferrer">http://external_ip:3000</a> it is not loading anything. How do I have to run my node app on <strong><em>external ip address</em></strong></p>
