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

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

I installed Docker-Toolbox just now while following their webpage

I started with Docker QuickStart Terminal and see following

                        ##         .
                  ## ## ##        ==
               ## ## ## ## ##    ===
           /"""""""""""""""""\___/ ===
      ~~~ {~~ ~~~~ ~~~ ~~~~ ~~~ ~ /  ===- ~~~
           \______ o           __/
             \    \         __/
              \____\_______/


docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com

bash-3.2$

But when I try to perform docker pull hello-world, this is what I see

bash-3.2$ docker run hello-world
Unable to find image 'hello-world:latest' locally
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.
bash-3.2$

What's wrong?

Solution

I had the same problem this morning and the following fixed it for me:

$ docker-machine restart default      # Restart the environment
$ eval $(docker-machine env default)  # Refresh your environment settings

It appears that this is due to the Docker virtual machine getting itself into a strange state. There is an open github issue here
