I just installed Streamlit. I wrote a hello world program. But no new tab opened in my browser, so I couldn’t see the result of my program.

HI @p0l4r ! Welcome to the community. :slight_smile: I’m sorry you had trouble seeing your app. So that I can help you better, could you please share the following information with me: Are you running this example on a local machine (e.g. your laptop) or a remote machine (e.g. an Amazon EC2 instan…

I am running the example on my personal computer ( local machine ). I ran streamlit hello. I have tried that. Didn’t work. I am using Windows 10 as OS and Google Chrome as web browser.

That’s super strange. To debug, I would like to see if the Python package we use to open the browser is working on your system. Can you try the command below in a Python interpreter (using the same environment you use for Streamlit): import webbrowser webbrowser.open('http://streamlit.io') And ju…

when I used- import webbrowser webbrowser.open(‘ http://streamlit.io ’) A new tab opened in my browser and I got redirected to http://streamlit.io when I used- import platform platform.system() This happened [image]

That’s very strange. What Streamlit does is just combine those two commands like this: if platform.system() == 'Windows': webbrowser.open(streamlit_url) So if that’s not working, I’m at a loss…

Actually, re-reading the thread I see you said that manually going the address displayed when you launch Streamlit doesn’t work. This makes me think the Windows Firewall may be blocking Streamlit. Can you look at the Firewall settings and see if Streamlit is allowed to access port 8501?

Can you please tell me how I do that ? I have tried different method, allowed streamlit application through firewall , but it is not working. I think I am not doing it right.

Hi @p0l4r , Sorry for the delay. I’ve been on-and-off trying to find some docs on how to do that, but could not find anything that looked promising. (Did I mention I’m not a Windows user? :wink:) So I have a couple more questions to help debug: When you run python -m http.server 8000 and go to h…
