The error “MariaDB connection refused” often denotes that an attempt to connect an app or client to the MariaDB database server was unsuccessful. Bobcares, as a part of our Server Management Service offers solutions to every query that comes our way.

Troubleshooting “MariaDB Connection Refused” Error

We can follow the below methods to fix the connection refused error in MariaDB.

1. Verify that the server is running the MariaDB service. We can start the service and check the status.

2. Make sure the application or client’s connection settings are correct. The database host, port, username, and password are all in in these settings.

3. Verify that no security groups or firewall rules are preventing incoming connections to the MariaDB port (the default is 3306). Examine the client-side and server-side firewalls.

4. Verify that the user trying to connect has the necessary privileges to access the database.

5. Check the resource usage in order to verify there is no overload, as excessive loads can prevent the creation of new connections.

6. Check the network link between the database server and the application if they are on different machines. Check for any network-related issues that may be causing the connection problem.

7. IP whitelisting may be enabled on some systems. Check that the IP address from which we are attempting to connect is permitted to connect to the MariaDB server.
