我更新了我们的一台服务器，并在服务器上安装了 Docker。在某种程度上，一切都成功了。我正在研究创建 Docker 映像的示例之一，但出现以下错误：
sudo docker run hello-world 无法在本地找到图像 'hello-world:latest' 拉取存储库 hello-world FATA [0162] 获取https://index.docker.io/v1/repositories/library/hello-world/images：拨打 tcp 162.242.195.84:443：连接超时
我正在与我们的网络管理员核实这一点，因为我能够通过浏览器浏览相关 URL 并获得以下 JSON：

搜索网络显示其他一些错误，但解决方案在这里不起作用。这可能是代理或端口问题吗？
我正在使用最新版本的 Docker
docker version
Client version: 1.6.1
Client API version: 1.18
Go version (client): go1.4.2
Git commit (client): 97cd073

FATA[0000] Get http:///var/run/docker.sock/v1.18/version: dial unix /var/run/docker.sock: permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?
当我运行时，docker pull hello-world我得到以下响应：

当我运行sudo docker pull hello-world时，即使我可以成功地卷曲 URL，我也会收到超时消息 -
