Can I Use Rancher 2.4 Dashboard Feature in Air-Gapped environment ?

Issue

In an Air-Gapped environment, when I try to access the Dashboard Feature, it is not working.
I keep having an error 500 from Rancher.

Pre-requisites

• Rancher 2.4.x
• Air-Gapped environment
• Experimental Dashboard Feature enabled.

Resolution

The Dashboard feature is still experimental and is currently not bundled in the Rancher releases.
It is currently hosted on https://releases.rancher.com/dashboard/latest/
This allow our Engineers to do some changes outside of the regular release cycle.

The same rules apply if the Kubernetes cluster is using a proxy.
The proxy should allow external access to this URL.
