Data Refresh failure in Power BI service

Hi Anonymous ，

Please download the latest version of Power bi Desktop and republish to Power bi services.

Then try publishing the report in a different workspace and refreshing it. If it works, you should remove it from the workspace where it was implemented and publish it again.
(Note: You need to delete this report and publish it again, not re-publish it from Power BI Desktop and replace it).

You can also see if this similar case is helpful to you:

Failure details: The last refresh attempt failed because of an internal service error. 

Hope it helps,
