Deploying streamlit app using pyngrok gettig error

I am getting this error while deploying streamlit app using pyngrok . I change port number but not able to solve this error.

, 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 connect: connection refused

Hi @shivu_sonwane,

Thanks for sharing with the Streamlit community!

Can you provide a code snippet that shows what commands you’re attempting to use to deploy with pyngrok?
