Hi All
Our platform allows users to configure and publish custom data endpoints for external consumption. We recently added the ability to surface the data as an OData feed, specifically for consumption in Dynamics and PowerBI.
As it stands we have the feeds being consumed successfully in C# code (via the OData connected service extension in Visual Studio) but when we try and access the endpoint in Dynamics or PowerBI we get a generic error message. We have tried simulating the request in PowerQuery and receive the following message.

We’ve tried comparing the data visually to reference datasources but so far are drawing a blank.
If there is someone there who can help it would be very much appreciated. An example of the data source would be https://kkapi.azure-api.net/api/Data/v1/eb68775b-c38a-490d-8866-ac1d0dc415e7/Employees?subscription-key=0c04173f848d4d37a56ae54bd93a5118
