Zend MySQL PDO and remote host fatal error SQLSTATE[HY000] [2002]

Question

At my local zend project I've got such problem, when I try to connect to remote mysql server.

Here application.ini part:

resources.db.adapter = PDO_MYSQL
resources.db.params.host = www.my-site.com
resources.db.params.port = 3306
resources.db.params.username = root
resources.db.params.password = 123
resources.db.params.dbname = mydb

When I refreshing page appears such error:

Fatal error: in D:\_www\enoiq.lcl\library\Zend\Db\Adapter\Pdo\Abstract.php on line 145

print_r($e->getMessage()); before line with error shows:

SQLSTATE[HY000] [2002] 

Where my mistake?

Thanks!
