Your health check is failing because Streamlit doesn't have a /health endpoint. In Railway settings: change health check path from /health to / (or remove it), set start command to streamlit run app.py --server.port=$PORT --server.address=0.0.0.0, and ensure the port is set to $PORT (not 8501). Railway assigns ports dynamically, so you must use their PORT environment variable, not a hardcoded port.

Can you please try using port 8080? Be sure the port set in railway match the one exposed by your app

I removed port setting from config.toml file, updated git repo and added that start command as you stated, it solved, problem was assigning port in config.toml file and manually in network settings.
