We have an odd behaviour we are trying to determine if this is "normal" behaviour. We have an RKE2 cluster provisioned by Rancher, and everything seems happy, however, we have multiple (5) control planes and on all but one, we get the following error:

W0812 09:52:59.453354       1 authentication.go:368] Error looking up in-cluster authentication configuration: Get "<https://127.0.0.1:6443/api/v1/namespaces/kube-system/configmaps/extension-apiserver-authentication>": net/http: TLS handshake timeout
W0812 09:52:59.453460       1 authentication.go:369] Continuing without authentication configuration. This may treat all requests as anonymous.
W0812 09:52:59.453465       1 authentication.go:370] To require authentication configuration lookup to succeed, set --authentication-tolerate-lookup-failure=false

However, on kube-scheduler-0, we don't get this "continueing without authentication" etc.
