Tenant Not authorized For Cluster

[elenaaaw]

In Power BI Report Builder i am trying to connect to a semantic model in the Power BI Service. I have a Pro license and I have made dozens of Paginated Reports with data sourced from a semantic model in the Power BI Service. This error has become a consistant issue that prevents me from doing anything in this app. 

Can anyone give me some more information on this error? How can I pinpoint the issue? How can I resolve this?

Hi @elenaaaw ,

This error typically means that your Power BI tenant (organization’s Azure AD instance) is not permitted to use the region-specific backend cluster that Power BI Report Builder is trying to connect to. It’s not about your Pro license or user permissions in the workspace, it’s about the connection between your tenant and the backend infrastructure hosting your datasets (semantic models).

Check for Recent Power BI Service region changes, have there been any tenant migrations, region changes, or new workspace creation policies enforced by your IT or Microsoft?
If your dataset is in a different region than your tenant, this might be the cause. You can confirm the region of a dataset in Power BI Service by going to:
Settings > Admin Portal > Tenant settings > Look under Data storage region.

Try accessing the same semantic model/dataset directly in the browser. If you can open it there, the issue is with Report Builder's connection or cluster authorization, not the dataset itself.

Occasionally, outdated builds or corrupted auth tokens can cause this:
Uninstall Report Builder completely
Reinstall the latest version from the official source,
Restart and re-authenticate.

Hope this helps,
Thank you.

We had this problem and the fix was to delete the msal.cache file in the 'C:\Users\<user>\AppData\Local\Microsoft\Power BI Report Builder' folder. It then asked to provide user account credientials when connecting to the Semantic Model Connections so once provided all worked as before.
