I keep getting a connection refused error when trying to connect to my MySQL database. I’m using Docker to run my application and everything was working fine before. The error message shows up whenever I try to establish a database connection. I’ve checked that MySQL is running but still can’t figure out what’s causing this issue. Has anyone encountered this problem before? I’m not sure if it’s a configuration issue with Docker or something else. Any suggestions on how to troubleshoot this would be really helpful.
Had the same connection refused error with Docker and MySQL. The problem was my app trying to connect to ‘localhost’ instead of the MySQL container name. In Docker, ‘localhost’ just points to your app’s own container - it can’t reach MySQL if it’s in a separate container. Change your connection string to use the MySQL container’s name as the host. Make sure both containers are on the same network and MySQL is fully up before your app tries to connect. If you’re using docker-compose, double-check your service names match exactly.
