Can't send mail in cakePHP3 from Godaddy

Can't send mail in cakePHP3 from Godaddy

I'm using Gourmet/Email and unable to send mail on Gadaddy from zoho.com hosted account, although everything was working well locally. My transport config is as follow : 

  1. 'default' => [ 'transport' => 'default', 'host' => 'ssl://smtp.zoho.com', 'port' => 465, 'username' => 'address', 'password' => 'pass', 'emailFormat' => 'both', 'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null), 'className' => 'Smtp' ],
I'm getting such a response :

Connection refused

Cake\Network\Exception\SocketException  

Can somebody help me fix this ?
