Can't connect to Flask web service, connection refused

I'm trying to run a simple web server on a Raspberry Pi with Flask. When I run my Flask app, it says:


running on http://127.0.0.1:5000/


But when I enter this address on my laptop's in Chrome, I get


ERR_CONNECTION_REFUSED


I can open 127.0.0.1:5000 on the Raspberry Pi's browser. What do I need to do to connect from another computer?

Answer

Run your app like this:

if __name__ == '__main__':
    app.run(host='0.0.0.0')

It will make the server externally visible. If the IP address of the machine is 192.168.X.X then, from the same network you can access it in 5000 port. Like, http://192.168.X.X:5000
