Grafana Dashboards not showing correct data from Promethus which is using Timescale db

[VIJAY-CH]

We have prometheus & grafana setup in Kubernetes.

Prometheu is using timescale as db and timescale mount to NFS for data storage.

We have configure prometheus datasource to Grafana and created dashboards.

Now the issue is :
When we look at the grafana dashboard, it is not fetching the correct data from prometheus and showing wrong data in dashboards.

Could you please help me here to get the correct data from prometheus to grafana.

Sometimes the dashboard showing the correct for 15 mins time range but its not showing the correct data for other time ranges like 1 hr, 3hr and 6r etc..

But whenever we checked in prometheus it is showing the correct data always.

Thanks.
