Forms Api

Hi

This is the first time I try to post a question on a community website. 

I am trying to access my forms data using the api to download an excel sheet to autotmate a dashboard that uses questionaire data. 

This worked perfektly fine a month ago, but now it says "The WWW-Authenticate header doesn't contain a valid authorization URI. Header value: 'Bearer'." Whenever I try to sign in to to the Organizational account. I have asked all relevant people in my organization, and they have not changed anything significant. I have tried from other acounts and from a older version. I am currently using the latest version of power bi desctop.  

Any ideas how to fix it? 

Kind regards 

Joachim
