Have an old cluster on a rancher server where the server certificate was updated and now this old downstream cluster can't come back online. Nodes can't see themselves (hostname not found). checksum shows it doesn't match in the agent pods, and kubeconfig connections get reset so can't be used. Is there any way to edit the docker command to fix the checksum values without having access to kubeconfig or the rancher UI for the cluster? (Locally, on the instance). rancher server itself is fine, and cluster instnaces are all running and were unchanged. Could I just run the docker agent join command again? or would that mess up the existing node
