Unable to create azure subscriptions : check the user has administrative privilages on the specific Azure account

Issue: 

I'm trying to restore whole VM in from Hyper-V backup job in to MS Azure. When I add account in to Veeam server getting below error,

"Unable to create azure subscriptions : check the user has administrative privilages on the specific Azure account "

We are not sure why Veeam is trying to create a new subscription while adding credential. Could you check and help us to check this case.

We found only below log in our log files

my Finding:

I have tried to add account under the version 10.0.1.4854 and got this error, however after I upgraded to veeam 11 it works fine.

Note : I believe this is Veeam version issue and raised the issue to Veeam Team but they refused it. Someone has same issues on Veeam 10 and fixed it?
