Failed to update data source credentials



I built a report in Power BI desktop from excel table stored in Sharepoint.

I published this report in power BI service and created a dashboard. 

Everytime I am trying to update the report I receive the following error message :

Make sure you skip Test Connection when you are doing your data source setting.

I have created a report using excel doc as web source from team site which works fine. When I published the report and try to refresh dataset from workspace I get Error "Processing errorThe credentials provided for the Web source are invalid. (Source at" . So I tried providing data source credential for dataset using OAuth2 authentication with Oragnizational privacy level , gives me similar error "Failed to update data source credentials: The credentials provided for the Web source are invalid. (Source at".


Looking for advice or anyone else had similar issue and were able to resolve it
