Get Started part 4 connection refused from node on virtual machine

Docker Engine Swarm

Confirmed, thank you @elavaud. If using VirtualBox, one can also set this environment variable first, then destroy your VMs and re-create them:

VIRTUALBOX_BOOT2DOCKER_URL=https://github.com/boot2docker/boot2docker/releases/download/v18.06.1-ce/boot2docker.iso

PS. If your docker-compose.yml file is set up like this (in Part 3)

ports:
  - "4000:80"

Then the URLs to hit in Part 4 will also need to specify port 4000.
