Some quick background: creating an app in golang, running on minikube on MacOS 10.14.2

The Issue: I cannot access my pod via it's pod IP from inside my cluster. This problem is only happening with this one pod which leads me to believe I have a misconfiguration somewhere.

My pods spec is as follows:

containers:
  - name: {{ .Chart.Name }}
    image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}"
    ports:
      - name: http
        containerPort: 8080
        protocol: TCP
    livenessProbe:
      httpGet:
        path: /ping
        port: 8080
      initialDelaySeconds: 60
    readinessProbe:
      httpGet:
        path: /ping
        port: 8080
      initialDelaySeconds: 60

What's weird is that I can access it by port-forwarding that pod on port 8080 and running curl localhost:8080/ping before the liveness and readiness probes run and after the pod has been initialized. This returns 200 OK.

Also during this time before CrashLoopBackoff, if I ssh into my minikube node and run curl http://172.17.0.21:8080/ping I get curl: (7) Failed to connect to 172.17.0.21 port 8080: Connection refused. The IP used is my pod's IP.

But then when I describe the pod after the initialDelaySeconds period, I see this:

  Warning  Unhealthy  44s (x3 over 1m)  kubelet, minikube  Readiness probe failed: Get http://172.17.0.21:8080/ping: dial tcp 172.17.0.21:8080: connect: connection refused
  Warning  Unhealthy  44s (x3 over 1m)  kubelet, minikube  Liveness probe failed: Get http://172.17.0.21:8080/ping: dial tcp 172.17.0.21:8080: connect: connection refused

Why would my connection be getting refused only from the pod's IP?

Edit I am not running any custom networking things, just minikube out of the box
