Could not connect to SMTP host PHP Mailer

Question

I'm using phpmailer to send email. This is my code.

require 'PHPMailerAutoload.php';

$mail = new PHPMailer;

$mail->SMTPDebug = 1;
$mail->isSMTP();                                      
$mail->Host = 'mail.distech.com.my';                    
$mail->SMTPAuth = true;                               
$mail->Username = 'myemail';                  
$mail->Password = 'mypassword';                          
$mail->SMTPSecure = 'tls';                          
$mail->Port = 587; 

I've used this code on my computer and it works. The email is been send. However, when I run this code on my friends computer, an error appears.

The error :

What could be the problem as I am new to phpmailer. I have tried pinging mail.distech.com.my on both computer and both works perfectly fine. Please help me thank you.
