Hello,

I’m using a Rancher 2.4.5, with 3 worker nodes and 3 etcd and control plane nodes.  
When one of the nodes becomes unavailable, my expectation is that the cluster will continue to run. But a specific node if it falls for the entire cluster. Rancher tries to communicate with the API through the IP of that specific node only and the message “ **Cluster health check failed: Failed to communicate with API server: etcdserver: request timed out** ” appears. How to do for Rancher to consult API from other control planes besides this one. Thank you.
