and have configured the Egress Gateway, Destination Rule & Virtual Service as shown below

While trying to access it throws an error
kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.7/samples/sleep/sleep.yaml -n akv2k8s-test
export SOURCE_POD=$(kubectl get pod -l app=sleep -n akv2k8s-test -o jsonpath={.items..metadata.name})
kubectl exec "$SOURCE_POD" -n akv2k8s-test -c sleep -- curl -sL -o /dev/null -D - https://edition.cnn.com/politics
kubectl logs -l istio=egressgateway -c istio-proxy -n istio-system | tail
How do I fix this?
