Re: Error Getting data via AS Connection Data source

Hi ,

The above error could occur when your email address which is used to sign in Power BI doesn’t match a defined UPN within the local Active Directory Domain. There are several proposals for you troubleshooting this issue.

Firstly, after you add SSAS data source under on-premises gateway, please check if the connection is successful by clicking the “Test all connections” button as shown in the following screenshot.


Secondly, please check that if the email address that you sign into Power BI service matches the defined UPN within the local Active Directory Domain following the instructions in this article. If your Power BI service login names do not match your local directory UPN, you can use the Map user names feature to create UPN mappings for Analysis Services Live connections that go through the on-premises gateway for Power BI. 



Thanks,
Lydia Zhang
