Hi @hillstone, I’m only guessing based on the limited information you’ve provided so far, but it sounds as if your windows firewall settings are blocking Streamlit from working correctly. I [found a page about Windows 2012 Enterprise firewall settings](https://support.rackspace.com/how-to/managing-the-windows-server-2012-firewall/). See if you can explicitly OPEN the streamlit port you’re running on (probably 8501) and then try it again. If that doesn’t work, let me know here and we’ll keep working on it. Good luck…! ---

Btw, I just answered another of your questions – should I assume you got streamlit working on Windows 2012? If so, could you write here how you solved the problem so it will help other people out? > [@The page cannot support the display of 120,000 records](https://discuss.streamlit.io/t/the-page-cannot-support-the-display-of-120-000-records/1842/2): > > Hi @hillstone, Without seeing your data I’m not totally sure what’s going on here, but at a size of 120K records it’s going to be one of two things. Maybe part\_df is very large, so your browser is having trouble rendering the page. Maybe creating part\_df is very resource-intensive because your dataset is not indexed on the right fields. Remember that Streamlit re-runs your script every time something happens on the front-end. So if you have any “greedy” operations that will fill your comput… ---

What browser are you using, and what version? If you have another browser installed, can you try that and type the URL [http://localhost:8501](http://localhost:8501) on that browser ---
