Before we progress any further, we should remove the hosts from within our herd. I would recommend launching the DigitalOcean control panel and terminating the droplets from there directly rather than using Rancher. In the past, I have had problems with timeouts and droplets that have not been fully terminated, which resulted in unexpected costs.

Terminate the three hosts, Rancher1, Rancher2, and Rancher3, and make sure they are no longer listed within your DigitalOcean control panel before moving on.
