Problem with dns in kibana - lb

Hi,
this is my kibana yml file:

apiVersion: kibana.k8s.elastic.co/v1
kind: Kibana
metadata:
  name: quickstart
spec:
  version: 7.6.2
  count: 1
  elasticsearchRef:
    name: cdbridgerpayelasticsearch
  http:
    service:
        spec:
            type: LoadBalancer
    tls:
      selfSignedCertificate:
        subjectAltNames:
        - ip: 160.46.176.15
        - dns: hulk.example.com

It ran very well:

$ kubectl get kibana

NAME HEALTH NODES VERSION AGE
kibana 7h11m

I can access the kibana with the external ip:

kubectl get svc
