Connecting to remote MySQL database via PHP

[David Schöfberger]

Hello everbody!

I have a problem with my settings in my MySQL database. I am currently using this php connection file with database from a hosting provider and it is working fine.

<?php
define('DB_SERVER',"servername");
define('DB_NAME',"database");
define('DB_USER',"username");
define('DB_PASSWORD',"password");

$conn = mysqli_connect(DB_SERVER, DB_USER, DB_PASSWORD, DB_NAME);
if(is_resource($conn))
{
mysqli_query($conn, "SET NAMES 'utf8'");
mysqli_query($conn, "SET CHARACTER SET 'utf8'");
}
?>

Now I got a virtual server from dediserve and I have installed apache, php, mysql and phpmyadmin and I wanted to used this php for connecting to the new mysql database, but it is not working (bind-adresses is hash tagged). That is the error:

Warning: mysqli_connect(): (HY000/2002): Connection timed out in /home/.sites/201/site2655003/web/temperature/03/inc/db.inc.php on line 7

The port 3306 is open and also configured as the standard port.

Can you help me? I have researched for hours in the internet, but its still not working!
