Is your web hosting server and MySQL in separate server? If so, do you configure your MySQL so the web server can access your MySQL database? You can create a simple php file to test MySQL connection if necessary:
<?php
$servername = “your_server”;
$username = “username”;
$password = “password”;
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die(“Connection failed: ” . $conn->connect_error);
}
echo “Connected successfully”;
?>
