Web browser does not open anymore

Hi everyone.
I’m using Streamlit internally for a while, and it is working fine.
Today, as always, I hit
streamlit run app.py as always and the web browser didn’t open.
I looked at other threads in the forum and nothing seems to work.

I am working with docker if it changes something.

What can I do?

@yuvalblau7 Do you need any help that how to laucnh streamlit via docker?
