title: Can't access my React App on Google Compute Engine
body: <p>I'm working on a webapp in ReactJS and I have to deploy it on Google Compute Engine. Here's my problem, when I connect to my instance and <code>git clone</code> my app, I do <code>npm i</code> <code>npm run build</code> and finally <code>serve -s build</code>. It's tell me that my app is served on <code>10.132.0.4:5000</code> (<code>10.132.0.4</code> is the private IP of my VM) but when I go to <code>my-public-IP:5000</code> with my browser, it loads for a while before to say me: <code>ERR_CONNECTION_TIMED_OUT</code>. I can't figure why, I can ping my-public-IP but if I try to telnet it on port 5000, it fails. Any idea ?</p>
