I ve just followed the steps of how to setup React App, wrote a small Hello World program based on the boilerplate found on App.js and then hit run to get the preview url.
I followed the url only to found a “no app seems to be running here” usual cloud 9 screen.
The message on the Idle makes it clear that is important to listen to the right port, ip.
For cloud 9 these are $IP and 8081 Port if I am not mistaken.
Now the question is: how do I set these in the (I presume) react-scripts>config> files?
Please help if you know how to resolve this.
