Data Source Credentials issue

Hi Anonymous ,

Could you please check What browser you use, if you use the Edge, you can have a try to change to the Chrome.

Or, because of your Data source is from Excel file to SharePoint url for Schedule refresh, you need to format the url.

powerbi - How to fix the message The OAuth authentication method isn't supported for this data source in Power BI? - Stack Overflow

Loading Excel Files from Sharepoint - (powerbi.tips)

You can check these documentations and follow the steps.

Or, there is an easy way to format: If your url have “x/r/”,  you have to strip out the :x/r/ from the middle of the URL and the question mark and everything after from the end and then it'll work.

Hope these help you.
