Proxmox VE 2.2 cluster config with unicast

We're pretty newbie to Proxmox VE, it's about 3 months that we use it with great success!!!

I've tried to config a cluster without HA usiing unicast since our provider, OVH, doesn't support multicast (except if we buy a vrack, but they still don't support vrack between two different DC).

I've done everything I've seen over the wiki and around the community, our server info are these:

# pvecm s
Version: 6.2.0
Config Version: 16
Cluster Name: pftech-cl1
Cluster Id: 45085
Cluster Member: Yes
Cluster Generation: 310296
Membership state: Cluster-Member
Nodes: 1
Expected votes: 1
Total votes: 1
Node votes: 1
Quorum: 1
Active subsystems: 5
Flags: 2node
Ports Bound: 0
Node name: xxxxxxx
Node ID: 1
Multicast addresses:
Node addresses:

# cat /etc/pve/cluster.conf
<?xml version="1.0"?>
<cluster name="pftech-cl1" config_version="16">

<cman two_node="1" expected_votes="1" keyfile="/var/lib/pve-cluster/corosync.authkey" transport="udpu">

<clusternode name="xxxxxxxxx" votes="1" nodeid="1"/>
<clusternode name="yyyyyyyy" votes="1" nodeid="2"/></clusternodes>


The problem is that, even if I can successfully add the second node without errors (even the waiting for quorum pass correctly), each server node cannot see the other node online, in fact:

~# cat /etc/pve/.members
"nodename": "xxxxxxxxxx",
"version": 15,
"cluster": { "name": "pftech-cl1", "version": 16, "nodes": 2, "quorate": 1 },
"nodelist": {
"xxxxxxxxx": { "id": 1, "online": 1, "ip": ""},
"yyyyyyyy": { "id": 2, "online": 0}

And on the other node I get the same for the first server.

I think there's something really easy to fix this but I really don't know how to get it works. Can someone help us?

Thanks in advance for your reply...
