Flask API was using PORT env variable which Railway also assigns to the frontend static server. Both services were competing for the same port, causing the container to fail health checks. Changed Flask to use FLASK_PORT (default 5000) so it runs independently from the Railway-assigned PORT used by the serve command. https://claude.ai/code/session_01YEMFAbGgf8K7as4Uqgjv3R
