Forbidden(403) message when run from Microsoft App

I have been using Companies House since long time, since last few months we didn’t perform any API checks. When I run the companies house check outside the Microsoft Dynamics 365 Customer Engagement it runs fine, but when I run from inside it shows Forbidden(403) Message.
While looking at the API status messages it appears the companies house has blocked the app IP address. Microsoft Dynamics 365 runs from the cloud and I do not have any access to IP address.
Can someone point me to the right direction?
