Symptoms

PLESK_INFO: ERROR: Zend_Db_Adapter_Exception: SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.
Additionally, an exception has occurred while trying to report this error: Zend_Exception
No entry is registered for key & #039 ;translate& #039 ; (Abstract.php:144)

"bind-address" parameter value in "%plesk_dir%"\MySQL\my.ini differs from the 127.0.0.1:

CONFIG_TEXT: bind-address=203.0.113.2

Cause

Incorrect IP address is specified in "bind-address" parameter in "%plesk_dir%"\MySQL\my.ini. Plesk connects to Plesk SQL Server service only on 127.0.0.1.

Resolution

Login to the server over RDP and remove "bind-address" directive from "%plesk_dir%"\MySQL\my.ini.
