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

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.
