Mysql distant connection with ssl

Hello,
I am trying to connect to a distant mysql but it is not working.
I have a "unable to connect to database".
Connection is working with a simple page php script.

Am I missing something?
my config ->

public $default = [
'DSN'      => '',
'hostname' => '192.168.1.10',
'username' => 'xxxx',
'password' => 'xxxxx',
'database' => 'xxxxxx',
'DBDriver' => 'MySQLi',
'DBPrefix' => '',
'pConnect' => false,
'DBDebug'  => (ENVIRONMENT !== 'production'),
'charset'  => 'utf8',
'DBCollat' => 'utf8_general_ci',
'swapPre'  => '',
'encrypt'  => array(
    'ssl_key'  => '',
    'ssl_cert'  => '',
    'ssl_ca'    => '',
    'ssl_capath' => '',
    'ssl_cipher' => '',
    'ssl_verify' => true,
),
'compress' => false,
'strictOn' => false,
'failover' => [],
'port'    => 3306,
];
