Alerting "NoData" in time series didn`t work

I try setting my notification`s with alert state NoData. (Grafana v9.2.2).
The task is that with the inaccessibility of one server or host, there is a notification that there is no data with that label
However, I faced the fact that either the notification works when Prometeus itself is unavailable or the notification on the label does not work.
I stopped node_exporter on server, but state was "normal"in preview alerts and doesn’t receive alerts.
Maybe I am not correctly setting up the Alert for warning or “NoData” doesn’t work. I can’t understand where it broke
