无法运行docker Hello-World

Question

Docker新手在这里！

我按照此说明安装了docker社区版（https://docs.docker.com/docker-for-windows/install/#start-docker-for-windows） 但是我收到了运行hello-world

的错误

PS C:\Users\ahkim> docker run hello-world
Unable to find image 'hello-world:nanoserver' locally
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
See 'C:\Program Files\Docker\Docker\Resources\bin\docker.exe run --help'.

我该如何解决这个问题？
