getting token error while connecting fabric warehouse from POWER BI DEKSTOP

Hi DiKi-I ,

Thanks for confirming that you've tried the suggested steps. Since the token error keeps happening, here are a few additional actions you can try that often resolve persistent token issues in Power BI Desktop:

1.Clear token cache folders under:
%LOCALAPPDATA%\Microsoft\Power BI Desktop\ and
%USERPROFILE%\AppData\Local\Microsoft\Power BI Desktop\AnalysisServicesWorkspaces
Then relaunch Desktop and sign in again.

2.Ask your IT Admin to check for:

Conditional access policies

Token lifetime settings

Any restrictions on Fabric access from desktop clients

3.Avoid preview Warehouse shortcut and instead try connecting via Get Data > Power BI Datasets or even OData Feed, depending on your Fabric setup.

4.Have your access to the workspace removed and re-added - this can often trigger the right token refresh behind the scenes.

5.If the issue persists, I recommend submitting your detailed feedback through Microsoft's official Support Ticket channels, such as the How to create a Fabric and Power BI Support ticket - Power BI | Microsoft Learn
