Mailer Error SMTP connect failed in php mailer https github com PHPMailer PHPMailer wiki Troubleshooting

Question

Here is code for sending email from localhost:

html form:

<form method="post" action="email.php">
  Email: <input name="email" id="email" type="text" /><br />

  Message:<br />
  <textarea name="message" id="message" rows="15" cols="40"></textarea><br />

  <input type="submit" value="Submit" />
</form>

email.php:

<?php

// $email and $message are the data that is being
// posted to this page from our html contact form
$email = $_REQUEST['email'] ;
$message = $_REQUEST['message'] ;

require_once('class.phpmailer.php');
require 'PHPMailerAutoload.php';
require 'class.smtp.php';

$mail = new PHPMailer();
$body='hellooooo';
$mail->IsSMTP();

$mail->Host = "ssl://smtp.gmail.com"; // specify main and backup server

$mail->SMTPAuth = true; // turn on SMTP authentication

$mail->Username = "xxxx@gmail.com"; // SMTP username
$mail->Password = "zzz"; // SMTP password
$mailer->SMTPSecure = 'ssl';
$mailer->Port = 465;//587;
$mail->AddAddress("xxx", "xx");
$mail->SetFrom('xxx@gmail.com','xxxx');
$mail->WordWrap = 50;

$mail->IsHTML(true);

$mail->Subject = "You have received feedback from your website!";

$mail->MsgHTML($body);

if(!$mail->Send())
{
echo "Message could not be sent. <p>";
echo "Mailer Error: " . $mail->ErrorInfo;
exit;
}

echo "Message has been sent";
?>

I am getting this error when I run the code

Message could not be sent.
