Loading the new Rancher Dashboard in an airgapped environment redirects to /fail-whale

Situation

Issue

When attempting to view the new Rancher dashboard in an airgapped environment, or one that requires a proxy to access the internet, the dashboard eventually times out and the user is redirected to https://rancher_server/fail-whale
Screenshot of error

Root cause

As the dashboard is currently in beta testing, the code for it resides in our CDN instead of being included in our images. The service responsible for pulling this code currently does not support proxy configuration.

Resolution

Until the dashboard goes into a General Release status, there is a requirement for internet connectivity to https://releases.rancher.com and https://github.com from both the Rancher cluster and also downstream controlplane nodes for this functionality to work.
