Failed to create nginx ingress controller

Question

After creating AKS cluster and trying to install nginx-ingress (following all steps from this article https://learn.microsoft.com/en-us/azure/aks/ingress-static-ip) I've got pending status on nginx-ingress-ingress-nginx-controller (pending external ip). External public ip is created in same group where kubernetes load balancer is.

kubectl describe service nginx-ingress-ingress-nginx-controller
gives such warning in events section

Events:  
  Type     Reason                  Age                 From                Message

  Warning  SyncLoadBalancerFailed  73s (x12 over 31m)  service-controller  Error syncing load balancer: failed to ensure load balancer: not a vmss instance  

What else can I check to find actual error, because this warning message gives no information at all on what is actually going on?

@Mark Kovarski Firstly, apologies for the delay in responding on this and any inconvenience this issue may have caused.

Since the warning you are getting are more of a generic one so I did some research and found that in most cases the possible reason is that your public IP is not in the same resource group and region with the AKS cluster.

You can get the AKS group through the CLI command like this:

az aks show --resource-group myResourceGroup --name myAKSCluster --query nodeResourceGroup
