I would like to use the fault injection mechanism of Istio.

I have been task to add a timeout of 5 second on a service. So to achieve this I made my own virtual service which follows:

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: hello
  namespace: default
spec:
  hosts:
  - hello-service.default.svc.cluster.local
  http:
  - fault:
      delay:
        percent: 100   #Applies on all request
        fixedDelay: 5s #Timeout of 5 sec
    route:
    - destination:
        host: hello-service.default.svc.cluster.local

As you can seen I only redirected the hello service on itself and applied the 5 second timeout. Unfortunatly the timeout isn't working at all...

This is the example from the documentation:

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: ratings
spec:
  hosts:
  - ratings
  http:
  - fault:
      delay:
        percent: 100
        fixedDelay: 2s
    route:
    - destination:
        host: ratings
        subset: v1

What am I doing wrong ?
Thx for your help

Update 1 - Adding targeted service

apiVersion: v1
kind: Service
metadata:
  name: hello-service
  namespace: default
spec:
  selector:
    app: hello
  ports:
  - port: 80
    targetPort: 9080

Update 2 - Adding output of proxy-config

$istioctl proxy-config route hello-75c874b67f-6l4p9
NOTE: This output only contains routes loaded via RDS.
