Problem with local server, starting react app

Question

When I am trying to 'npm start' react app https://github.com/0wczar/airframe-react and then go to local server at http://0.0.0.0:4100/ I got ERR_ADDRESS_INVALID. What should I do to repair my local server?

@JuChengJiang The question is about IP addresses. It isn't specific to React or Python. — Code-Apprentice, Nov 13 '19 at 18:30

You are entered the wrong server URL. It should be localhost or 127.0.0.1, I think.

http://localhost:4100

or

http://127.0.0.1:4100

Thanks! http://localhost:4100 works. But why it's that URL? When vs code tells me that it should be http://0.0.0.0:4100/? – modsell Nov 13 '19 at 18:30
@modsell `0.0.0.0` is not a valid address. See the link below your question for an explanation. – Code-Apprentice Nov 13 '19 at 18:31
