PHPMailer - SMTP Error: Could not connect to SMTP host - php

Question

I'm trying to send email using PHPMailer. When I tried sending the email from gmail account, it works perfectly fine. However, I would like to send the email from my own SMTP, but there seems to be an error. What could be the problem? Please help me. Thank you.
Using smtp.gmail.com :
$mail->SMTPDebug = 3;
$mail->isSMTP();
$mail->Host = 'smtp.gmail.com';
$mail->SMTPAuth = true;
$mail->Username = 'myemail#gmail.com';
$mail->Password = 'password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;
Using mail.distech.com.my :
require 'PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->SMTPDebug = 3;
$mail->isSMTP();
$mail->Host = 'mail.distech.com.my';
$mail->SMTPAuth = true;
$mail->Username = 'myemail#distech.com.my';
$mail->Password = 'password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;
$mail->From = 'myemail#distech.com.my';
$mail->addAddress('amalina#distech.com.my');
$mail->Subject = 'Test';
$mail->Body = 'Test message';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
