Hi guys, I'm currently facing a strange situation since upgrading to rancher 2.6.9 with a downstream RKE2 cluster. The cluster is usable, I can see all workloads, I restarted all controlling services, everything, but rancher still tells me:

Cluster health check failed: Failed to communicate with API server during namespace check: Get "<https://10.43.0.1:443/api/v1/namespaces/kube-system?timeout=45s>": context deadline exceeded

😠 did anybody come across this strange situation and has an idea on how to fix it? I'm using rancher since many years and could fix so many strange issues, but this is really weird
