🔧 Troubleshooting

Database Connection Error

Error: Access denied for user 'root'@'localhost'

Solution: Check DB_USER and DB_PASS in .env

Port Already in Use

Error: listen EADDRINUSE: address already in use :::3000

Solution: Change PORT in .env or kill process using port 3000

JWT Secret Warning

Warning: Using default JWT secret

Solution: Set JWT_SECRET in .env to a strong random string
