如何解决如何使Kubernetes仪表板的Kubectl代理正常工作？
我正在运行ubuntu服务器20.04的三台服务器上建立一个高可用性的microk8s集群。 我启用了仪表板插件，并尝试使用命令转发它
kubectl port-forward -n kube-system service/kubernetes-dashboard 10443:443
在WSL Ubuntu中，在kubeconfig文件中配置了microk8s集群，但返回了错误
error: error upgrading connection: error dialing backend: dial tcp 192.168.250.235:10250: connect: no route to host
因此，我尝试在其中一台服务器上运行microk8s dashboard-proxy来查看是否可以正常运行，并返回错误
Checking if Dashboard is running.

在microk8s集群中启用了插件面板，dns，ha-cluster，helm3和metrics-server。
kubectl get nodes返回以下输出：
