Error due to SMTP connection failed.So, Check your configuration first, you can check by comment the line $mail->IsSMTP();

// $mail->IsSMTP();

See below is working demo :

  <?php
   require 'phpmailer.php';
   require 'smtp.php';
   $mail = new PHPMailer;
  //$mail->IsSMTP(); // telling the class to use SMTP
   $mail->Host       = "smtp.gmail.com"; // SMTP server
   $mail->SMTPDebug  = 1;                     // enables SMTP debug information (for testing)
                                       // 1 = errors and messages
                                       // 2 = messages only
   $mail->SMTPAuth   = true;                  // enable SMTP authentication
   $mail->Host       = "smtp.gmail.com"; // sets the SMTP server
   $mail->Port       = 465;                    // set the SMTP port for the GMAIL server
   $mail->Username   = GMAIL EMAIL ID; // SMTP account username
   $mail->Password   = GMAIL PASSWORD;        // SMTP account password
   $mail->SMTPSecure = 'ssl';


   $mail->From = '[e-mail]';
   $mail->FromName = 'Mailer';
   $mail->addAddress('MAIL ID to whom you eant to send');               // Name is optional

  $mail->addCC('CC EMAIL ID');
  $mail->addBCC('BCC EMAIL ID');
  $mail->WordWrap = 50;                                 // Set word wrap to    50 characters

  $mail->Subject = 'Here is the subject';
  $mail->Body    = 'MESSAGE';
  $mail->AltBody = 'This is the body in plain text for non-HTML mail  clients';

  if(!$mail->send()) {
  echo 'Message could not be sent.';
  echo 'Mailer Error: ' . $mail->ErrorInfo;
  } else {
  echo 'Message has been sent';
 }
    ?>
