I have a google Kubernetes Engine running. I made an ASP.NET core MVC application that is deployed as a service on the engine and I would like to be able to make an HTTP request (GET http:serviceendpointip/controller/action) to this service from a different application. I tested my MVC application using ngrok (provides a public url to my application) and the request worked successfully.

So my application seems to be working fine. However, when I deploy it as an exposed public service to the Kubernetes engine, the request is not working and I am assuming that the engine is somehow blocking this network traffic... I am able to view the application's homepage on http://serviceendpointip/home from a web browser. What could be causing my HTTP request to be failing?
