Swiftmailer and smtp gmail in yii2 - yii2

Question

I tried to configure swiftmailer in yii2 advanced. I read the tutorial and I use the code in here, but I'm still got an error.
In my case, guest must submit his name and his email before download Ebook. And then, they will get an email from my office which contains an ebook download link.
My configuration in common/config/main-local.php
'components' => [
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
'viewPath' => '#common/mail',
'useFileTransport' => false,
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'smtp.gmail.com',
'username' => 'myaccount#gmail.com',
'password' => 'password',
'port' => '465',
'encryption' => 'ssl',
],
],
],
In my controller/GuestController.php
public function actionCreate()
{
$model = new guest();
if($model->load(Yii::$app->request->post())){
return Yii::$app->mailer->compose()
->setFrom('myaccount#gmail.com')
->setTo($model->email)
->setSubject('halo')
->setTextBody('body')
->send();
$model->save();
return $this->redirect(['buku/index']);
}
else{
return $this->renderAjax('create',[
'model' => $model,
]);
}
}
Form Guest
<div class="guest-form">
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'nama')->textInput(['maxlength' => true]) ?>
<?= $form->field($model, 'email')->textInput(['maxlength' => true]) ?>
<?php
echo Alert::widget([
'options' => [
'class' => 'alert-warning',
],
'body' => '[Alert] Check your email for Download',
]);
?>
<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
<?php ActiveForm::end(); ?>
And my error,
Swift_TransportException Connection could not be established with host
smtp.gmail.com [ #0]
How can I fix this? Thank you, It's Solved

I have always used the settings with encryption as tls and port 587 and you dont need to set the 'useFileTransport' => false, as now it defaults to false see here
'mailer' => [
'class' => 'yii\swiftmailer\Mailer' ,
'viewPath' => '#common/mail',
'transport' => [
'class' => 'Swift_SmtpTransport' ,
'host' => 'smtp.gmail.com' ,
'username' => 'myaccount#gmail.com',
'password' => 'password',
'port' => '587' ,
'encryption' => 'tls' ,
] ,
] ,
