Hi team,
so we deploy the latest version of Kubernetes cluster then suddenly rancher stopped working,
An error likes this
2022/05/18 07:21:50 [ERROR] error syncing 'c-m-j9mfddmt/p-n9tdv': handler system-image-upgrade-controller: upgrade cluster c-m-j9mfddmt system service alerting failed: template system-library-rancher-monitoring incompatible with rancher version or cluster's [c-m-j9mfddmt] kubernetes version, requeuing
after some research, many have this issue and can go back to normal after rolling back the k8s version.
But we use managed Kubernetes service so the only option was to delete the cluster.
And still have this error
