Cannot join K8S cluster to Rancher

Hi everyone, I am using Kubernetes version 1.286. I want to join my cluster to Rancher, but It happen issue as below, my Rancher is version latest
Please help check, thank you!


I can suggest only a workaround not a solution.

Please check if there is data in the secrets named like “custom--machine-plan” in the fleet-default namespace.

If no data, try register another node with all roles (–etcd --controlplane --worker)

This will generate another secret, hopefully containing the data.
