when i try to join a rke2 worker to the cluster using the registration command in rancher, it seems to install everything, but fail on this error in syslog level=error msg="failed to get CA certs: Get \"\": EOF" now, if i edit /etc/rancher/rke2/config.yaml.d/50-rancher.yaml and replace the ipv6 address of one server there, with the loadbalancer's address for the supervisor service, and reboot the node, it joins and seems happy. but the original ip address of one server is restored to that file. is this single server ip in /etc/rancher/rke2/config.yaml.d/50-rancher.yaml expected ? is it possible to inform rancher of the loadbalancer ip somewhere ? do describe the need for a fixed registration address, but not where you would put that in the rancher gui when creating the cluster. I do not think it is the authorized endpoint address?
