Colab: Unable to access webpage using flask-ngrok

[krypticmouse]

I'm trying to run flask application on colab but I keep seeing the following when I go to the tunneled page:-

Code:-

# flask_ngrok_example.py
from flask import Flask
from flask_ngrok import run_with_ngrok

app = Flask(__name__)
run_with_ngrok(app)  # Start ngrok when app is run

@app.route("/")
def hello():
    return "Hello World!"

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

I have the same problem, we need to put the authtoken into the configuration file of the ngrok, but i dont know how, because we don't have the acess of this file.
