WWW-Authenticate header doesn't contain a valid authorization URI

[Anonymous]

Hi,

My dashboard is connected to Microsoft Forms via the API "https://forms.office.com/formapi/DownloadExcelFile.ashx?".

It has been working well until yesterday, when I got this message:

I have tried changing the permissions, and even create a new data source, but with no help.

Anyone has any idea how to resolve this?

Thank you!

Hi  @Anonymous ,

Try clearing all permissions to see if you are prompted for credentials the next time you run the query. Depending on your system, try different options such as windows or organizational accounts.
