SharePoint On Premises with FBA authentication enabled issue on PowerBI

[Vikasmattela201]

I am trying to connect SharePoint On Premises site which has windows and FBA (Form based authentication). Tried with windows credentials to authenticate Sharepoint from PowerBI. But getting "Authentication Error" issue.

Hi @Vikasmattela201

Does this "Authentication Error" only occur in Power BI Desktop? Are you able to access the same sharepoint on-premises site in a web browser on your computer with the same windows credentials? Please have a test.
