Rancher and my raspberry pi

I’ve got Rancher setup but when I attempt to pull in my PI cluster running k3s I get the following error on my PI

cattle-cluster-agent-86697b44c8-kw74c 0/1 CrashLoopBackOff 6 (101s ago) 7m24s

more info

Warning Unhealthy 3m (x3 over 3m25s) kubelet Readiness probe failed: Get “”: dial tcp connect: connection refused

I’ve been looking to see if I can find something but I cannot seem to pull anything up on this. Any help appreciated.
