php - PHPMailer wont Work 000webhost

I have enabled less secure apps on my account but still the same error.
Message could not be sent.Mailer Error: SMTP connect() failed

I tried with a free host 000webhost. Here is my code

    require 'PHPMailerAutoload.php';

    $mail = new PHPMailer;

    //$mail->SMTPDebug = 3;                               // Enable verbose debug output


    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = 'leets@gmail.com';                 // SMTP username
    $mail->Password = 'private';                           // SMTP password
    $mail->SMTPSecure = 'ssl';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 465;                                    // TCP port to connect to

    $mail->setFrom('leets@gmail.com', 'tEst');
    $mail->addAddress('leets@gmail.com');     // Add a recipient

    $mail->addAddress('ellen@example.com');               // Name is optional
    $mail->addReplyTo('info@example.com', 'Information');
    $mail->addCC('cc@example.com');
    $mail->addBCC('bcc@example.com');

    $mail->isHTML(true);                                  // Set email format to HTML

    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'Hello ,Click On the link to reset password';
    $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';
    }
    ?>
