Hi,
we have Veeam Backup and Replication v13, Community Edition, Build 2067 on Microsoft Windows Server 2019 with Hyper-V.
When I try to add a Veeam Data Cloud Vault from the Austria East Region I get the following error:

The error occurs during authorization of the backup server after I login using Microsoft, including MFA and after I answer the question if I want to stay signed in (Yes or No has the same effect).
If I add the same VDCV Repo on another installation of Veeam (different customer, paid version) it works.
I installed the Veeam Console on the only VM of the server and I got the same error.
AI suggested to check the version of a specific DLL, which is 2067.
I installed a trial license, same error.
I disabled all security filtering on the firewall temporarily and checked the logs.
Any ideas, how this can be fixed?
Thanks a lot for your help!
Thomas
