Kubernetes Dashboard Ingress returning empty response from server - kubernetes

Question

I am trying to set up the kubernetes dashboard. I have enabled the custom ssl certs from my domain and can curl the pod directly with no issues - i can curl the service and it works with no issues. However, when I try to access via ingress I get (52) empty response from server. I have an NLB forwarding to the port of nginx controller service (ingress works fine with another app). Here is my ingress config:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
labels:
app: dashboard
name: dashboard-ingress
name: dashboard-ingress
namespace: kubernetes-dashboard
spec:
rules:
- host: k8sdash.domain.com
http:
paths:
- backend:
serviceName: kubernetes-dashboard
servicePort: 443
path: /
Here is the Daemonset config for my ingress controllers.
