Data Refresh Internal Service Error

Hi all,

Having an issue with my data refresh. I keep getting an Internal Service Error. I have a SQL Server on premise data source that outputs data to an Azure Blob. The Azure blob is then used as a power bi data source. 

On the server I have a Microsoft Data Management Gateway installd. It is up to date and connects to the database just fine. I also am using the updated version of Power BI desktop to build the dashboards and publish to the service.

Unsure of what could be casuing this issue. Any help would be greatly appreciated.
