How to solve Swift_TransportException Connection to ssl Timed Out error?

问题

I have a problem send email using Yii, the problem is sometime it result in ssl timeout, but some time mail send is going well.

The error says something like this

 Swift_TransportException

 Connection to ssl://in-v3.mailjet.com:465 Timed Out

Here is the error image

After reading some article, it's looks like because socket is timeout so it should start socket again.

Here is my article that I read.

swiftmailer and Yii2 not working 1 out of 10 time

How to close Smtp connection in SwiftMailer

Here is my config in common\config\main-local.php

'mail' => [
  'class' => 'yii\swiftmailer\Mailer',
  'viewPath' => '@backend/mail',
  'useFileTransport' => false,
  'transport' => [
      'class' => 'Swift_SmtpTransport',
      'host' => 'in-v3.mailjet.com',
      'username' => 'myUserName',
      'password' => 'myS3cr3tP4ss',
      'port' => '465',
    'encryption' => 'ssl',
  ],
],

Here is how I send email in my controller

$message = Yii::$app->mail->compose();
if (Yii::$app->user->isGuest) {
  $message->setFrom('from@domain.com');
} else {
  $message->setFrom(Yii::$app->user->identity->email);
}
$message->setTo(Yii::$app->params['adminEmail'])
->setFrom(Yii::$app->params['adminEmail'])
->setTo($model->email)
->setSubject('Reset Password')
->setHtmlBody($this->renderAjax('//email/_content',['content' => 'email content goes here']))
->send();
return $this->render('confirmation_sent');

How I can stop and start connection with my above code?

I have already put this code exactly before $message

if (Yii::$app->mailer->getTransport()->isStarted()) {
    Yii::$app->mailer->getTransport()->stop();
}
Yii::$app->mailer->getTransport()->start();

But it still show SSL time out sometimes.

I ask about this problem to mailjet, and got this response

Hi, Thank you for your reply.
Ok, please try with port 443 with SSL or: 25,80, 2525 with no encryption, 587 and 588 with TLS.
Let me know if it works.

Already try all the port with given encryption but it's remain the same, sometime I meet Timed Out

UPDATED

Using try catch give me Failed to authenticate on SMTP server with username "a3027c30a1c1f6f60d2f9d7813360b46" using 3 possible authenticators1 some times.

Using try catch give me Connection to ssl://in-v3.mailjet.com:465 Timed Out too, it show sometime.

Here is my traceroute from our server to mailjet

Is this because different Yii::$app->mailer to start stop socket and Yii::$app->mail to send email?

Am I right these error because ssl socket is stopped? Please explain me too how come this error appear.

Thanks in advance.

You have an error because it can not connect to the smtp and the time for attempts is over. Try to change the port and encryption, maybe this will help you but I'm not sure. It depends on your n-v3.mailjet.com, what settings he needs, I do not know.

'mail' => [
  'class' => 'yii\swiftmailer\Mailer',
  'viewPath' => '@backend/mail',
  'useFileTransport' => false,
  'transport' => [
      'class' => 'Swift_SmtpTransport',
      'host' => 'in-v3.mailjet.com',
      'username' => 'myUserName',
      'password' => 'myS3cr3tP4ss',
      'port' => '587',
      'encryption' => 'ssl',
  ],
],
