Power BI Online return Credential Invalid Error on Anonymous Access of API URL

Hello Vicky_Song and ttinsley

I will consider this case closed.

I had to replace all of our connections to the webservice for connections in a newly created database on Microsoft Azure.

Now we can refresh the dataset normally.

But I think that problem with the refresh using the webservice is linked to the fact that the Power BI Service performs the same call multiple times.

See the image below of my webservice LOG:

We would appreciate it if one day it is resolved.
