Thanks
@creamy-pencil-82913, the rke nodes were restarted with no effect. I tried also the upgrade to v1.24.17 +rke2r1 but the critical after was always present. Today the cluster was working and the alert disappeared, maybe related to
https://github.com/prometheus-community/helm-charts/issues/3441 , I suspect the promql query that trigger the alert has some issues when the certificate is just refreshed.
