Navicat Connection Database Configuration Checklist

When connecting to a Navicat database, you should check the following: Make sure that the target database is listening for a connection and that the port matches the Navicat configuration. Enter the correct username and password and confirm that the user has connection permission. Verify that the network connection is normal and make sure that the routing is correct. Check that the connection settings are compatible and try other connection options if necessary. Check that the target database is started and check for connection errors in the log.
