Try restarting the monitoring by running tiup cluster reload <cluster_name> -R grafana,prometheus,alertmanager and check again.

Executed this reload, but it doesn’t seem to work.

After executing the reload, it recovered after 10 minutes. Thank you.

If you encounter issues with Grafana, Prometheus, or Alertmanager that cannot be resolved in the past few days, you can directly scale down and then scale up Grafana, Prometheus, and Alertmanager.
