php - SMTP Connect() failed. Message was not sent.Mailer error: SMTP Connect() failed

Question

Am trying to send mail to a gmail address but it keeps on getting this error "SMTP -> ERROR: Failed to connect to server: Connection timed out (110)SMTP Connect() failed. Message was not sent.Mailer error: SMTP Connect() failed." What could be the problem?

        require 'class.phpmailer.php'; // path to the PHPMailer class
        require 'class.smtp.php';

            $mail = new PHPMailer();


            $mail->IsSMTP();  // telling the class to use SMTP
            $mail->SMTPDebug = 2;
            $mail->Mailer = "smtp";
            $mail->Host = "ssl://smtp.gmail.com";
            $mail->Port = 587;
            $mail->SMTPAuth = true; // turn on SMTP authentication
            $mail->Username = "[email protected]"; // SMTP username
            $mail->Password = "mypasswword"; // SMTP password 
            $Mail->Priority = 1;

            $mail->AddAddress("[email protected]","Name");
            $mail->SetFrom($visitor_email, $name);
            $mail->AddReplyTo($visitor_email,$name);

            $mail->Subject  = "Message from  Contact form";
            $mail->Body     = $user_message;
            $mail->WordWrap = 50;  

            if(!$mail->Send()) {
            echo 'Message was not sent.';
            echo 'Mailer error: ' . $mail->ErrorInfo;
            } else {
            echo 'Message has been sent.';
            }

Remove or comment out the line-

$mail->IsSMTP();

And it will work for you.

I have checked and experimented many answers from different sites but haven't got any solution except the above solution.
