Streamlit hello throws error

I am trying to run a streamlit server in my docker. I have managed to install streamlit in my docker however when I try to run command “streamlit hello” it will throw error and state that streamlit did not auto detect external ip. May I know what is wrong here or what step am I lacking?

Only see one network url: http://172.20.0.2:8501

Please give us a bit more information and show us at least your Dockerfile.
