No one likes to see an error like the following when running the Plesk Panel:
ERROR: PleskMainDBException No connection could be made because the target machine actively refused it. 0: common_func.php3:619 reconnect() 1: common_func.php3:582 db_connect() 2: auth.php3:14
It is basically a message indicating that Plesk cannot connect to MySQL.
- Confirm both services (MySql Server and Plesk SQL Server) are running.
- Check Windows firewall rules
- Verify that the file \Plesk\MySQL\Data\my.ini is using the correct SQL port: 8306.
