Create-react-app, npm start but no preview



I want to run an app using create-react-app on cloud9 aws, but after doing npm start and clicking on the link there is no preview! Of course I read answers like “Try running the app through (aka $IP ). The preview URL picks up by default; localhost won’t work.”.

But seriously I don’t understand how to do :face_with_raised_eyebrow:

Is someone would be nice enough to help me to pass throught this simple problem, because I am sure I miss something obvious… thank you



is there someone who can explain??
