App Not Refresh or to dataset

[Anonymous]

Hi Experts

I have a Finance App which is not refresh error message this report could not access the data source. 

I am Admin on Gateway and have user on all the data sets and i have set up refreshes which refresh the datasets in the Workspace 100%.

The Source is SSAS Cube. Which is import mode to the data as the data source has been set up with Window Auth. I do believe its not Direct Query Mode. 

Not sure where to look when it comes to the app and how to resolve the issue

Hi @Anonymous 

Can you confirm that you have set up the data source connection to your SSAS cube using a Windows account which has Admin rights on the SSAS Cube?
