V2.2.x restore etcd database

I am really struggling testing a restore from backup documented here “https://rancher.com/docs/rancher/v2.x/en/backups/restorations/ha-restoration/“. I have built 3 new nodes, brought them up to an installed rancher version, placed the local v2.2.7 snapshot which was snapshotted with rke v0.2.7. The restore rke was v0.2.8. All returns ok but rancher pods don’t restart complaining about “Waiting for server to become available: the server has asked for the client to provide credentials” I can do a helm version fine but an helm ls returns Error: Unauthorized, any ideas.
