Hi, after banging my head around for some time, I still can’t manage to get the following command working, thanks in advance!

$sudo docker run hello-world

Unable to find image ‘hello-world:latest’ locally docker: Error response from daemon: Get [https://registry-1.docker.io/v2/:](https://registry-1.docker.io/v2/:) dial tcp 52.54.216.153:443: getsockopt: connection refused. See ‘docker run --help’.

I am using **CentOS7** virtual machine on VirtualBox with HTTP/HTTPS/FTP proxy settings configured at system level. This proxy configuration has been working fine for Chrome and other applications.

Here is the version of Docker on my virtual machine:

$sudo docker version

Git commit: 9ee9f40
