EasyShip vs Magento 2 not getting a enabled plugin but I do see a connect on the platform. API ip needed

Hi all,

I am testing easyship for the first time.When I activate the plugin I see a new connector in the easyship platform but the plugin status in magento is still disabled and I do not see any shipping option in the checkout (enabled in shippingmethods)

I do think I know what the problem is, our nginx authentication on dvl and test. Which I am not able to remove due to my hoster. So now the question is how can I whitelist the easyship connection / api ? Can somebody tell me the IP addresses used?
