无法连接到服务器：连接超时（110）SMTP Connect（）失败。 邮件未发送。邮件错误：SMTP Connect（）失败

Question

This is my code and still it is not sending the mail. 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->Mailer = "smtp";
            $mail->Host="smtp.gmail.com";
            $mail->SMTPSecure='tls';
            $mail->Port =465;             
            $mail->SMTPAuth = true; // turn on SMTP authentication
            $mail->Username = "mymailgmail.com"; // SMTP username
            $mail->Password = "mypassword"; // SMTP password 
            $mail->SMTPDebug = 1;

            $mail->AddAddress("mymail@gmail.com","Title");
            $mail->SetFrom($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.';
            }

// header('Location: thank-you.html'); }

I had similar issue sometime back. It turned out that the connection was attempted using ipv6 address. It worked fine after removing IPv6 address from network interface.
