问K8S集群，metrics部署错误,如何修正？

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-systemNAME                              READY   STATUS    RESTARTS   AGEmetrics-server-56f864bddc-nfg2t   1/1     Running   4          12d kubectl get svc -n kube-systemNAME             TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                  AGEmetrics-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 apiservicesNAME                                   SERVICE                      AVAILABLE                      AGEv1beta1.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
