<p>a bit of background is that I have setup an Azure Kubernetes Service cluster and deployed a basic .Net Core api as a deployment object. I then deployed a nodeport service to expose the api and then deployed a nginx-controller and an ingress object to configure it. I use the IP of the ingress-controller to route the request and that works eg.<a href="http://1.2.3.4/hello-world-one/api/values" rel="noreferrer">http://1.2.3.4/hello-world-one/api/values</a>.
But when I replace the Ip with the generated dns, somehow the path is ignored and I get the default backend - 404 returned from the nginx controller. The expected behaviour is that the dns will resolve then the path "api/values" will be sent to my service.</p>

<p>Can anyone help me with this?
Thanks in advance.</p>

<p>My deployment, service and ingress configs are below.</p>

<p>pretty sure <code>rules</code> should look like this:</p>

<pre><code>rules:
