Application Gateway fronting Speckle on Kubernetes

Hi @iainsproat yes we have but we get the following on the application gateway backend health

Received invalid status code: 404 in the backend server’s HTTP response. As per the health probe configuration, 200-399 is the acceptable status code. Either modify probe configuration or resolve backend issues.

On the application gateway the backend pool is pointing to my-private-dns.io
I created a debug pod and run a curl on the private dns name (please see below) and got nginx which suggests the private dns has been resolved. Also the same dns is in the values file and when I look at the speckle namespace ingress its using the same dns

root@aks-nodepool1-12581264-vmss000000:/# curl http://my-private-dns.io
