我想控制我的远程k8s集群，但是有问题
我有k8s集群管理员提供的kubeconfig文件。但是，当我尝试连接群集时，我却犯了一个错误，当使用浏览器获取时-结果还可以
kubectl version --kubeconfig ./.kube/config -v=12 --insecure-skip-tls-verify=true --alsologtostderr
I0211 18:13:42.625408 12960 loader.go:359] Config loaded from file ./.kube/config
...
I0211 18:13:54.691273 12960 helpers.go:216] Connection error: Get https://k8s-t-deponl-01.raiffeisen.ru:8443/version?timeout=32s: Tunnel Connection Failed
