There is no recipe for the hydraneckwebrtc-controller role. The controller must be set up manually (config, systemd service, moonlight-web-stream binary). The worker recipe (hydraneckwebrtc-linux.yaml) exists but does not cover the controller.
Create hydraneckwebrtc-controller-linux.yaml recipe that provisions:
