Grafana only shows 24h block with last 30 days in time range dropdown

I dont know why i can’t see more data for last 30 days. the time range selector is 30 days, and i know i have this data.
Its a problem of configuratión? What have i do? Thanks in advance

what is your prometheus and are you receiving the data for 30 days if you check your raw request and response in the panel --> inspect modal?

the problem wasn’t of grafana. I have a architecture prometheus+thanos+grafana. I needed add the storage connector handle by thanos to prometheus.
Grafana was showing 2 hours blocks stored in prometheus sidecar.
Thanks for your support.
Kind regards
