Fatal error: Uncaught GuzzleHttp\Exception\RequestException

[Samirgitthub]

When I try to execute(with the my_ name of thing filled in)

require "vendor/autoload.php";
$client = new Shopify\PrivateApi(array(
    'api_key' => 'my_api_key',
    'password' => 'my_password',
    'shared_secret' => 'my_shared_secret',
    'myshopify_domain' => 'myshopify_domain.myshopify.com'
));
$service = new Shopify\Service\ProductService($client);
$service->all(); 

I get this error:
