Can't connect to Flask web service, connection refused

Question

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/

Answer 1

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
