laravel connect to online database

I have offline application (installed in localhost) but database in online server.. because i want to make something like synchronizer...

I've tried to set my database.php like this

       'mysqlserver' => array(
            'host'      => '103.38.103.142',
            'port'      => '212',
            'driver'    => 'mysql',
            'database'  => 'lgspsb',
            'username'  => 'xxxxxxx',
            'password'  => 'xxxxxxx',
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
        ),

but error like this...

SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading initial communication packet', system error: 0 

How I can't fix that? thanks before... and sorry for my bad english
