Can't connect to tenant assigned Azure Data Lake Gen 2 storage account

My Power BI admin has connected a tenant assigned Azure Data Lake Gen 2 storage account in Admin Portal > Azure Connections. We followed the steps as per the documentation  

The storage account is
  • in the same location then my PBI tenant (in my case North Europe)
  • HNS is enabled
  • Power BI admin has Owner role assigned in the storage account

I created a new PPU workspace with Dataflow storage (preview) enabled. 




Then as a workspace admin I opened the Workspace Settings > Azure Connections where the checkbox for Use the default Azure connection was not checked, I selected/checked it, and there is no apply button on it. I navigate out of Workspace Settings and then navigate back to Workspace Settings of the same workspace to find the check box is again not selected.  



When I check the storage account, the powerbi and powerbi-backup folders are created there. Then I created and refreshed a dataflow in the same workspace, but the data is not populated in tenant-assigned ADLS Gen 2 storage account.

Has anybody faced the same issue? Is it a bug? Kindly help with the same!

Hi @tabina 


Check the following aspects

  • Permissions Check: Ensure that the Power BI service principal has the necessary permissions on the storage account. This is crucial for writing data to the ADLS Gen2 account.

  • Dataflow Configuration: Verify the dataflow settings within the workspace to ensure they are correctly pointing to use the tenant-assigned ADLS Gen2 storage. Sometimes, manual adjustments might be needed to ensure the dataflow is correctly configured to use the external storage.

Hi @tabina 


If you had previously connected a workspace and then remove the connection, this will be causing the error you are experiencing. What I would suggest doing is to remove the folder from the storage account and then try and recreate the connection
