Streamlit webpage not displayed

I am a new user and I have a problem with the basic use of this extension.
I work on a server that is not connected to the Internet and when I open the browser it does not show me the information that I built, it looks like it is trying to connect and fails.

Is there a way to overcome the problem or do I must an Internet connection?

Thanks for the help and patience.
