Laravel 5.3 connect to remote sql server

I am building a laravel application that requires to connect to sql server and fetch some data . i have already put my credentials in database config file as follows

'sqlsrv' => [
            'driver'   => 'sqlsrv',
            'host'     => env('SQL_HOST'),
           // 'port' => env('SQL_PORT'),
            'database' => env('SQL_DATABASE'),
            'username' => env('SQL_USERNAME'),
            'password' => env('SQL_PASSWORD'),
            'charset'  => 'utf8',
            'prefix'   => '',
        ],

Unfortunately when a run my queries i get this error

PDOException in Connector.php line 55:
SQLSTATE[HY000] Unable to connect: Adaptive Server is unavailable or does not exist (severity 9)

Can anyone please suggest on the workaround to solve this problem . i am suing Godaddy shared hosting . when i read other posts , they say that the solution is to use freetds as shown here . If this is so , how i am suppose to implement that ?
