Hello, I have upgraded my rancher from 2.7.1 to 2.8.4. I have 3 nodes for Rancher all consist of Control Plane, Etcd. One node of three is working and the other two are not. I get the following error: level=info msg="Waiting to retrieve kube-proxy configuration; server is not ready: https://127.0.0.1:9345/v1-rke2/readyz: 500 Internal Server Error" Not sure what my issue is anymore. Tried several things but cant get it to work

did you upgrade rancher, or rke2? The Rancher version deployed to the cluster has nothing to do with the RKE2 version that the cluster nodes are on.

rancher

was the rke2 node down before you upgraded rancher, or ?

no it was functioning
