I upgraded 3 instances of rancher to rancher 2.13.0 yesterday. each instance has about 5 clusters. In one of the instances one downstream cluster got stuck on control-plane upgrading where api-server complained about ipv6 address not matching cidr ipv4 address. I then checked the control planes /etc/rancher/rke2/config.yaml.d/50-rancher.yaml and did see that they had an ipv6 address in node-external-ip and not the ipv4 address of the node. I made a /etc/rancher/rke2/config.yaml.d/99-rancher.yaml where I did override this on the two control plan nodes, rebooted them, and it started working again, and cluster got green again. Now when I check for node-external-ip I see that some but not all etcd nodes in that same cluster also has ipv6 address and not ipv4. This despite that cluster was provisioned with ipv4 only in networking part in Rancher UI. Anyone have any idea why that happened and how to properly fix it? This is an onprem install using vmware provisioning of nodes
