I cannot connect MYSQL when I'm usıng to my Domain.

When I entered domainname/phpmyadmin I can Connect MYSQL without any error.

But, I cannot connect MYSQL when I’m usıng connect.php file. connect.php files include: <?php $servername = “domaınname”; $username = “root”; $password = "**";

// Create connection $conn = mysqli_connect($servername, $username, $password);

// Check connection if (!$conn) { die("Connection failed: " . mysqli_connect_error()); } echo “Connected successfully”;*

and I’m writing this to firefox : domainname/connect.php I get thıs error Connection failed: Can’t connect to MySQL server on ‘domainName’ (111)

thank you
