Network timed out while trying to connect to https://index.docker.io

Question

I installed Docker-Toolbox just now while following their webpage

I started with Docker QuickStart Terminal and see following

Answer 1

I installed Docker without the Toolbox on Windows 10, so the version that requires Hyper-V to be enabled.

For Docker version 1.12 I had to go into the taskbar, right click the Docker Icon, select Settings -> Network and set the DNS Server to fixed, so that is uses Google's DNS server at 8.8.8.8.

Once that setting was changed, it finally worked.
