I've written and deployed an asp.net core 3 web api REST service to our server on our network, which is hosted in IIS, and sending HTTP requests to the service works using Postman. Now I am writing a Xamarin app which needs to connect to this service. All this will be from within our network, so the server is referenced by name and its IP address is always an internal one. When debugging the app in Visual Studio, I cannot reach the server.
The Xamarin project is UWP and Android, and so far I've only been testing on UWP. I can get a response from google.com, but not from our internal server either by name or internal IP address.
