我在这里跟随Docker教程：withExcept :: (e -> e') -> Except e a -> Except e' a
我能够运行docker search whalesay暗示初始设置正在运行。
我尝试了Error response from daemon: Get https://index.docker.io/v1/search?q=whalesay: dial tcp: lookup index.docker.io on 192.168.0.1:53: read udp 10.0.2.15:58317->192.168.0.1:53: i/o timeout
，但收到此错误
docker pull hello-world运行Using default tag: latest
Pulling repository docker.io/library/hello-world
Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/hello-world/images. You may want to check your internet connection or if you are behind a proxy.
会提供此输出

我不确定这里的问题是什么。我需要研究哪些网络设置？
