I have a custom node that I am trying to join to our cluster. The rancher agent is getting stuck in this loop (https://github.com/rancher/rancher/blob/release/v2.9/pkg/rkenodeconfigclient/client.go#L149) and from what my team has been able to trace is receiving a 503 error from rancher server manager. Engine: RKE1 Cluster k8s version: v1.24.13 Agent version: 2.6.8 Rancher server manager version: v2.6.8 Has anyone run into this or have information or things to try to get around it?
