Unmanaged cluster gets stopped by firewall

The error isn't about failing to contact the Hemiron repository; it's about the inability to deliver the application from the repository to your local, unmanaged cluster.

The "connection refused" error is a direct and valuable result for your research. It demonstrates a core concept: a standard CI/CD runner hosted on the internet cannot reach a private, local Kubernetes cluster. This limitation is precisely why alternative models like GitOps (your next PoC step) were invented.
