python - Flask server returns 404 on localhost:5000 w/ Twilio

Question

I'm following this guide (Python Quickstart: Replying to SMS and MMS Messages) to try and set up a flask server, but when I try to connect to http://localhost:5000 I get a 404 error. I can ping 127.0.0.1 no problem.

Code:

from flask import Flask, request, redirect
import twilio.twiml

app = Flask(__name__)

@app.route("/", methods=['GET', 'POST'])
def hello_monkey():
    """Respond to incoming calls with a simple text message."""

    resp = twilio.twiml.Response()
    resp.message("Hello, Mobile Monkey")
    return str(resp)

if __name__ == "__main__":
    app.run(debug=True)

Console output:

 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with windowsapi reloader

localhost 404'ing

Answer 1

I can connect to http://127.0.0.1:5000/ after restarting my computer. Not sure what was causing the issue.
