Advanced Yii 2.0 Swiftmailer does not work with gmail

Question

I am trying to configure swiftmailer in an extended yii 2.0 template. I went through a lot of messages, and I understand that there are some problems with gmail. My development environment in development is as follows:

'mailer' => [
        'class' => 'yii\swiftmailer\Mailer',
        'viewPath' => '@common/mail',
        'useFileTransport' => false,
        'transport' => [
            'class' => 'Swift_SmtpTransport',
            'host' => gethostbyname('smtp.gmail.com'),
            'username' => '[e-mail]',
            'password' => 'xxssxxxx',
            'port' => '465',
            'encryption' => 'ssl'
        ]

I also installed the support email that was used in the controller to the same gmail address in the main local config shown above. I tried switching to a less secure configuration for applications in my gmail account, and it didn’t work, and I don’t really like to change it. I get the following error when I use ssl encryption

unable to connect to host ... [# 0]

If I do not specify encryption, I get a timeout error.

OpenSSL phpinfo, . TLS , , (: '587' encryption = 'tls'),

stream_socket_enable_crypto(): SSL 1. OpenSSL : : 14090086: SSL: SSL3_GET_SERVER_CERTIFICATE:

, ? ? ?
