Power BI Service Refresh Not working

Hi, Prashant_leo 

First verify that the gateway version is the latest version. You can check the following link:

Verify that the report has a gateway selected. If you don't select a gateway, the data source may have changed or been lost.
Make sure that all data sources are authenticated correctly and check if your credentials have expired.

Check for errors in Power Query. If you're dealing with massive datasets, it can cause problems. Long-running queries can cause timeouts. Or maybe there might be an issue with the Power BI service itself and you need to wait for a while. You can check the following link:
