Azure Data Lake Gen2 Storage - http status:['Unauthorized']

[PMGJwat]

Sorry to bother, I'm usually able work out issues with a bit of googling however this one has me pulling my hair out.  I have tried to log a support ticket but i cant find my premier access ID or contract password, i dont think we even have them without paying extra for support. 

Setup
PPU licenses 
UK Business
2 Workspaces, the one having issues is the one connected to a Data Lake Gen2 Storage Account. 

Since Friday all the dataflows have been failing on this Workspace. 
A configuration error was encountered while using ADLS filesystem: Forbidden. error message: '' http status:['Unauthorized']"}

When testing the azure connections for the same blob storage within Manage Connections and Gateways

I have tried to change the connection within the workspace settings however it will not alow me to save. This Storage account is brand new and has 0 files within it. 

i have also tried to run a deployment pipeline to move all the flows to a new workspace so i can set this up again however this errors.

After 4 days this resolved itself.

Hi @PMGJwat,

Thank you for reaching out to Microsoft Fabric Community Forum.

The error indicates that Power BI is unable to validate the dataflow. Please follow the steps below to resolve the issue:

verify the dataflow credentials, navigate to Power BI Service and access the relevant workspace. Open the dataflow and review its data source settings. Ensure that the authentication method is set to OAuth2 for Azure Data Lake Gen2.

check the ADLS Gen2 connection, go to Manage Connections and Gateways in Power BI Service. Validate that the connection to Azure Data Lake Storage Gen2 is active and does not display any errors, confirming a successful integration.

If this post helps, then please consider Accepting as solution to help the other members find it more quickly, don't forget to give a "Kudos" – I’d truly appreciate it!

@Anonymous thanks for the response

Connection is setup for Azure Datalake with OAuth 2.0

however it does display this at the top

within the datasource settings it set up with OAuth2

with all of this its still failing to do any refreshes for these dataflows. Am i missing something.
