Fix Database Connection Post-Deployment

Deployment (Hostinger + GitHub) Project Overview I'm looking for an experienced Node.js/Express developer who is familiar with Hostinger VPS/Web Hosting, GitHub deployments, MySQL, and CORS. The frontend is already online, but the backend API cannot connect to the MySQL database after deployment...
