Qdevice not voting in my cluster

To preface, I am completely new and I have no idea what is going on, so bare with me.

I am trying to set up a qdevice to be the third vote in my cluster, but it won't vote. Logs seem to show everything is working fine but maybe I don't understand what logs I need to look at, I have no idea where to even start really. I can ssh between the qdevice and the nodes, node to node, and node to qdevice. I've reinstalled everything and reconfigured things, I am totally lost. I've spent 40 minutes googling to no end, at some point I think I saw someone was complaining that there was a bug for this with VE 8.1?

Here is where I am at, and I'll put the corosync.log below this:

These are the logs from corosync.log on the qdevice from my last attempt:

Ahhh. All the nodes in your cluster need to communicate to the Qdevice on tcp port 5403 as well.

Is there a firewall or similar that needs to be adjusted to let traffic from the nodes through to the Qdevice?

Once that communication path is working, the Total votes count in Votequorum information should increment to 3, and the vote count for the Qdevice in the Membership information should change to a 1, something like this:

Code: 
Votequorum information
----------------------
Expected votes:   3
Highest expected: 3
Total votes:      3
Quorum:           2
Flags:            Quorate Qdevice

Membership information
----------------------
    Nodeid      Votes    Qdevice Name
0x00000001          1    A,V,NMW 192.168.2.104 (local)
0x00000002          1    A,V,NMW 192.168.2.106
0x00000000          1            Qdevice

Thanks so much, that's probably it!

I am going to write this down to try later. I just set up my experimental homelab which doesn't actually need to be in a cluster, I only wanted to try a cluster because it seemed fascinating and I wanted to learn more about it. For now I will just have isolated nodes which will work just fine for what I am doing right now.

I will probably create a proper 3 node cluster in the future when I've got the cash to do so, I already had a pi running so I thought to at least try it. I did learn a decent bit even though I did not accomplish my goal!
