Permission denied when deploying to Streamlit cloud on port 80

I have an app at https://leetcode-scoreboard.streamlit.app and I’m getting an error PERMISSION DENIED. From the traceback, I don’t think it has anything to do with any of my dependencies.

I’m using Python 3.11 and Streamlit 1.40.1.

Hey, @streamLIT-af

Sorry for your inconvenience. I found the reason, you are defining port in your config.toml configuration. Streamlit application cannot start on protected port (80). We are going to change the code on our side to ignore that configuration. You can simply remove it from configuration and app is starting as expected

That was the problem, thank you!
