We have the same problem, and been at this for a few days without progress. We have 3 nodes STORAGE NIC1 and Storage NIC2 on each server are connected to VLAN 711 and 712 respectively. All nodes are the same. The Storage NICs have an APIPA address. No VLAN set on the NICs. We start the deployment and all the the times we get errors like these
