The logs failed during the cluster build step, which happens in node 3 deployment. It failed to build the Consul server, which is the first service we use that relies on the backend network. It is most probably due to incorrect backend network settings:

"backend_1_base_ip": "134.137.0.0",
"backend_1_eth_name": "eth3",
"backend_1_mask": "255.255.0.0",
"backend_1_vlan_id": "",
"backend_2_base_ip": "134.137.0.0",
"backend_2_eth_name": "eth4",
"backend_2_mask": "255.255.0.0",

Here both backend 2 and backend 1 are using overlapped addresses 134.137.0.0. The tcp/network layer can get confused it may send a backend 1 packet sometimes on eth3 other times eth4, this will cause packet not being received. To fix:

"backend_1_base_ip": "134.137.0.0",
"backend_1_mask": "255.255.0.0",
"backend_2_base_ip": "134.138.0.0",
"backend_2_mask": "255.255.0.0",

and modify the backend 2 ip assigned to each node.

It is probably possible for you to change the config files/reboot..but is probably easier and quicker to install from start
