Dear all
I am trying to connect to my Azure subscription with the Azure version of ArcGIS Enterprise Cloud Builder.
However, I am not able to connect.
First of all, when I open the application and press "Sign in to Azure" seems that the app. tries to connect...After that a first message is shown: "You do not have any Azure Subscription. Please, sign up for one". If I specify a Azure subscription....I get the next message:

My question is: where can I review the details? Is ther any log file or something similar? Any idea about what's happening?
Thank you in advance
