Yii2 Swiftmailer cannot send mail from a different server other than gmail, I can not understand why?

When sending mail with gmail all works fine, as soon as apply server settings which I gave admin to email all the flies and gives an error, help to understand.
Configure mailer
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
'viewPath' => '@common/mail',
'useFileTransport' => false,
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'mail.chumak.net',
'username' => '******',
'password' => '******',
'port' => '587',
'encryption' => 'tls',
And error that gives now.
stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Get encryption at all or change the tsl to ssl. Apparently it is in the certificate.
changed tsl to ssl and now this error
