Lost connection to MySQL server during query

Jeg prøver at få forbindelse til min MySQL database fra en ekstern server med dette PHP script:

$hostname = "207.44.160.85";
$username = "root";
$pw = "xxxxxx";
MYSQL_CONNECT($hostname,$username,$pw);
mysql_select_db("$dbName");

Jeg får denne fejl:


Warning: Lost connection to MySQL server during query in bah.php on line 47

Warning: MySQL Connection Failed: Lost connection to MySQL server during query in bah.php on line 47


På trods af at jeg har denne bruger i MySQL og jeg HAR genstartet MySQL:
