我在裸机上运行Kubernetes，并使用Kubernets仪表板来管理集群。最初，此功能运行良好，但尝试访问仪表板的时间为5-30分钟后：
http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
我收到以下错误：
错误：“拨号TCP 10.35.0.19:8443：连接：主机没有路由” 尝试到达：“ https://10.35.0.19:8443/”
如果我用kube-system检查它们，kubectl get pods -n kube-system中的所有Pod都已启动并正在运行：

当我使用kubectl delete pods --all -n kube-system重新启动此命名空间中的所有Pod时，仪表板有时会再次工作5-30分钟，有时它会随机再次开始工作。我尝试过分别重新启动此命名空间中的每个Pod，以尝试跟踪导致此问题的Pod，但是一个接一个地重新启动Pod不会使仪表板再次启动。只有一次全部删除命令有效。
有人知道为什么会发生这种情况以及如何解决吗？ 预先谢谢你！
