I want to integrate streamlit app with google colab. I followed this tutorial But after running ngrok.connect is shows this error. Anybody faces this? I have tried kill process of ngrok, but nothing works.
On localhost

On Ngrok.io
Failed to complete tunnel connection
The connection to http:XXX.ngrok.io was successfully tunneled to your ngrok client, but the client failed to establish a connection to the local address localhost:80.
Make sure that a web service is running on localhost:80 and that it is a valid address.
The error encountered was: dial tcp 127.0.0.1:80: connect: connection refused
