Constantly getting alert for targets down

Hi I have installed grafana 9.0.5 using promtheus operator. So I have been observing 2 alerts firing in grafana alert that

1: KubeControllerManagerDown
KubeControllerManager has disappeared from Prometheus target discovery.
2: KubeSchedulerDown
KubeScheduler has disappeared from Prometheus target discovery.

and I have followed some solution like changing the binding address of kube system config from 127.0.0.1:10249 and others but there is no luck and I am constantly getting that alerts.
Can you please help me on this.


I have attached the screenshot of that file can you please check and confirm.
