ok ... i fixed the problem but i need some explanation (or fixing my system ...)
the second node (second proxmox server in the data center ) got a faulty NIC (probebly becose of the power outage) so the second server did not make any connection at all after NIC replacement everything working grate

so ... when i have a data center i can get locked out if one of my server die ???

If the cluster is not quorate [1] (which is the case, if one of your only two nodes is offline = no majority online), yes.
With only two nodes, it is highly recommended to either add a third node or at least add a QDevice [2] on an additional independent system.
