Changing network (or network DNS) breaks connection to docker.io

This morning I was able to run aldryn project workon for a project at home; when moved to my office later in the day I would consistently get an error

Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/postgres/images. You may want to check your internet connection or if you are behind a proxy.

After finally deleting and recreating the Virtual Box VM, it worked again. Then on returning home, it failed with the same error, until I once more deleted and recreated the VM.

@GaretJax speculated this may be due to different network/DNS addresses at the two locations.

If this is the case, then the Docker configuration needs to be robust enough to handle this.

@evildmp Nothing we can do there since we don't configure the user's shell nor system. However we do now provide many helpers in aldryn doctor which helps tackling those issues. Closing here.
