    1. Ingress: Verify Ingress annotations (kubernetes.io/ingress.class: azure/application-gateway), service name/port, and path rules.
    2. AGIC: Check AGIC logs (kubectl logs -n kube-system <agic-pod>) for errors. Restart AGIC if needed.
    3. Service: Ensure service selector matches pod labels (kubectl get pods --show-labels, kubectl describe service <service>).
    4. Pods: Confirm pod IPs are in the Application Gateway's VNET (kubectl get pods -o wide).
    5. Azure Portal: Check Application Gateway backend pool health, listener, and rules, verify health probe path/port in service/ingress matches app, Check NSGs/UDRs for conflicts.
