This command (with kubectl 1.11+) will show you what resources remain in the namespace:

# kubectl api-resources --verbs=list --namespaced -o name \
  | xargs -n 1 kubectl get --show-kind --ignore-not-found -n <namespace>

# kubectl port-forward  service/argo-cd-argocd-server -n argocd --address 192.168.109.100 8080:443
