error external image via rest api

Hello,

I get following error when i create product via rest api.

Automattic\WooCommerce\HttpClient\HttpClientException  : Error: Fout tijdens het verkrijgen van externe afbeelding https://images.wehkamp.nl/i/wehkamp/16201949_pb_01.jpg?w=500&h=500. Fout: Forbidden [woocommerce_product_image_upload_error]

I already tried to remove: ?w=500&h=500 with no luck.
I also tried via http url instead of https, also with no luck.

I can add other products with images with no problems.

i use: https://packagist.org/packages/automattic/woocommerce version 3.0.0.
Woocommerce: 3.7.0
Wordpress: 5.2.2

        $woocommerce = new Client(
            'https://XXX.com',
            'ck_XXX',
            'cs_XXX',
            [
                'wp_api' => true,
                'version' => 'wc/v3',
                'query_string_auth' => true
                'timeout' => 120,
                'verify_ssl' => false
            ]
        );

What can be the problem?

kind regards.
