K8S集群，metrics部署错误

metrics-server pod 部署成功处于running状态，服务也处于running状态

kubectl get pod -n kube-system
NAME                              READY   STATUS    RESTARTS   AGE
metrics-server-56f864bddc-nfg2t   1/1     Running   4          12d

kubectl get svc -n kube-system
NAME             TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                  AGE
metrics-server   ClusterIP   10.96.165.35   <none>        443/TCP                  12d

但是，执行在master节点执行kubectl top pods 报错：
W1212 13:09:35.004801 8720 top_pod.go:140] Using json format to get metrics. Next release will switch to protocol-buffers, switch early by passing --use-protocol-buffers flag
Error from server (ServiceUnavailable): the server is currently unable to handle the request (get pods.metrics.k8s.io)
查询apiserver，发现检查可用性失败

kubectl get apiservices
NAME                                   SERVICE                      AVAILABLE                      AGE
v1beta1.metrics.k8s.io                 kube-system/metrics-server   False (FailedDiscoveryCheck)   12d

查看pod，metrics-server，apiservice， v1.certificates.k8s.io 详细信息未见错误
连接服务地址测试，ping 10.96.165.35通
telnet 10.96.165.35 443不通，所以访问服务地址不通
curl https://10.96.165.35/apis/metrics.k8s.io/v1beta1
只有在metrics pod所在的工作节点执行telnet 10.96.165.35 443可通，请问如何修改，在master节点可以使用kubectl top pods命令
