I’m new to Streamlit and Nginx in general, and I am trying to deploy streamlit on my server and use nginx to reach the app through my domain url.

I reached the point now where when trying to access my domain while Streamlit is off, the error 502 bad gateway is displayed. When running streamlit hello, I get nothing but a blank page. Although the page’s title is shown as “Streamlit” . So I guess I am not too far from reaching my goal, could anyone give me some light on what to edit? The app is perfectly reachable (through http) when I type in the server’s IP and the relevant port, though. Running python3 -m http.server 8501 and opening my domain’s url displays a file explorer.

Here are my nginx site configuration and streamlit files (edited mostly according to this post). I also add a screenshot of the errors shown in Chrome console.

Thank you very much already!
