kubectl version Client Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.2", GitCommit:"66049e3b21efe110454d67df4fa62b08ea79a19b", GitTreeState:"clean", BuildDate:"2019-05-16T16:23:09Z", GoVersion:"go1.12.5", Compiler:"gc", Platform:"linux/amd64"} Unable to connect to the server: EOF

我用kubectl去查看版本都会报这个EOF的错误，求解

请检查下 kube-nginx 服务是否正常，后端配置的 kube-apiserver 节点 IP 和端口是否正确。

检查一下你的kube-apiserver是否启动，一般是你的apiserver状态异常。你看一下是什么状态。systemctl status kube-apiserver

本地安装的话可以检查下是否配置了https_proxy代理，我也碰到这个问题了

unset http_proxy && unset https_proxy && unset ALL_PROXY
