I think in Proxmox at the moment it cannot begin with a number, thanks for your help. It still does not seem logical to me hence a Realm eg on FreeNAS can begin with a number, and it is not documented for the error messages. The most I know it is not important for me to understand this limitation or feature of proxmox, I am thankful I got it working... have a great day/evening.
