+WARNING: NetworkPolicy + Ingress are both enabled.
+The default NetworkPolicy allows port {{ .Values.service.containerPort }} only from pods within
+namespace {{ .Release.Namespace }}. Ingress controllers typically run in a separate
+namespace (ingress-nginx, kube-system, etc.) and will be blocked.
+To allow ingress-controller traffic, add a namespaceSelector rule:
+
+  kubectl edit networkpolicy --namespace {{ .Release.Namespace }} {{ include "openconcho.fullname" . }}
+
+  # Under spec.ingress[0].from, add:
+  - namespaceSelector:
+      matchLabels:
+        kubernetes.io/metadata.name: <ingress-controller-namespace>
