Cannot open console on 1 out of my 3 nodes

I have 3 nodes - pve1, pve2, pve3. I usually log into pve1 as they are in a cluster I can see the others an manage them fine. I am using the free update repository right now - JUST starting to use this in production in a startup business - cash strapped, so can't do paid support option yet.

So, anyway, I run updates every week or 2 (have been testing for a while). It always works fine - except today. When I click on Upgrade - it opens a console window - but it ends up stopping with "Disconnecting... (Detecting Migration...)" and I get an error in the Tasks list a the bottom of the screen. The error is for Shell - the error reads: "failed waiting for client: timed out - TASK ERROR: command '/usr/bin/termproxy 5900 --path /nodes/uwpve1 --perm Sys.Console -- /usr/bin/pveupgrade --shell' failed: exit code 1"

Additionally, I can't open a console to any of my VMs via pve1 either. The console window says "Failed to connect to server". The Task list shows an error for that VM console simply saying "connection timed out".

But, if I log into either pve2 or pve3 - they can update/upgrade and open the console windows fine. It doesn't matter which machine the VM's are located on. The pattern in the same. Pve 1 cannot open consoles on itself or any other node, but the other 2 nodes can open the console to VMs on itself or the others - including pve1.

I've made no changes to Proxmox on any of these machines. So I don't know what started this.

Thanks!
 
Well, it started doing it to both and I think I resolved it. It seems to be related to a MTU change on a VPN connection I was using. After lowering the MTU on my VPN connection - all 3 nodes are now showing the consoles fine.
