Sharing does not work on some browser under some unknown conditions

Last time I found in my chrome browser the code becomes not work any more (Connecting to Streamlit server Forever). That problem solved by itself after a few days (maybe after a chrome update or something similar).

Yesterday I want to share my app to one of my colleagues and I find the similar problems occur in her computer too. The page just keeps blank and I guess it might be also a connection problem.

I think this really hurts the usability and reliability of streamlit. Is there any advise or suggestion on this issue?
