Im trying to restore a failed rke2 cluster from an etcd snapshot. However, when i follow https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/backup-restore-and-dis[…]tore-rancher-launched-kubernetes-clusters-from-backup on two different etcd snaphots (two different nodes), after editing yaml and getting the etcd restore, i always get "non-ready bootstrap machine(s) custom-xxx and join url to be available on bootstrap node" , what am i doing wrong?
