Node can't ping another node after reboot no Corosync

[CelticWebs]

I rebooted a node and now I'm unable to get sync with it, I get the error Cannot initialize CMAP service. I can;t get it to launch VMS due to lack of Quorum. I also can't do vvecm expect 1 as I get the same error about CMAP service.

I'm able to due apt update so I have network. I am unable to ping the other node and the other node is unable to ping this node.

cat /etc/pve/.members on the faulty node shows

{
"nodename": "pve847",
"version": 0
}
root@pve847:~# cat /etc/pve/.members
{
"nodename": "pve847",
"version": 0
}

The same command the node that is up and running says

{
"nodename": "prox380",
"version": 3,
"cluster": { "name": "CelticWebs", "version": 2, "nodes": 2, "quorate": 1 },
"nodelist": {
  "prox380": { "id": 1, "online": 1, "ip": "X.X.X.X"},
  "pve847": { "id": 2, "online": 0}
  }
}

I noticed firewall was enabled with no options, not sure how or why as its was a new install. Wasn't able to disable it in GUI due to the error telling me it can't lock a file and no quorum. I disabled this via command line but still no dice!

I've looked at the corosync file and they both look the same. I'm at a loss. What can I do to find out why they can't talk and get the server back online?

***Update***
turning off the firewall did actually allow the devices to ping each other. Still no sync though

currently I managed to stop corosync and work in local mode, just to get vms up.
