Traefik ingress with External-DNS Statuscode=409

Traefik Traefik v2
1

i'm using aks cluster and traefik ingress and i'm using external-dns to update my records . i installed my traefik ingress and he's working fine this my variables for helm :

additionalArguments:
  - "--accesslog=true"
  - "--accesslog.format=json"
  - "--log.level=DEBUG"

deployment:
  replicas: 1

service:
  spec:
    loadBalancerIP: 20.151.201.38
  annotations:
    "service.beta.kubernetes.io/azure-load-balancer-resource-group": "aks-test"

kubernetesIngress:
  publishedService:
    enabled: true

and this is my ingress manifest :

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: my-ingress
  namespace: default
  annotations:
    kubernetes.io/ingress.class: traefik
    traefik.ingress.kubernetes.io/router.entrypoints: web
    external-dns.alpha.kubernetes.io/hostname: app.juicyreviewz.com
    external-dns.alpha.kubernetes.io/target: juicyreviewz.com
spec:
  rules:
  - host: app.juicyreviewz.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: app1-nginx-service
            port: 
              number: 80

and after running this manifests the record is created but i got this error from external-dns pod :

time="2023-01-11T14:50:57Z" level=info msg="Updating CNAME record named 'app' to 'juicyreviewz.com' for Azure DNS zone 'juicyreviewz.com'."
