Cannot ping local or external network

So I made a mistake while trying to switch IP's for the vmbr0 holding my proxmox IP, on my main node within a cluster.
Well, I can log into the node now on iLo, but I can't access web GUI or ping anything at all. I'm honestly not sure what happened.

I've checked the typical '/etc/hosts, /etc/corosync/corosync.conf, and everything within the /etc/pve/..' dir to make sure it's set correctly, but there's something I'm missing here.

Any help at all would be appreciated.

What about the actual network config file: /etc/network/interfaces?
Please provide the full output in code-tags of:
  • cat /etc/network/interfaces
  • ip a
  • ip l
  • pvecm status

do you have any trace of something related to your nics in #dmesg or /var/log/kern.log* ???

when you have changed your ip, do you have rebooted on a newer kernel ? (maybe a kernel driver bug ?)
I'm seeing a lot of:

"vmbr1: port 2 entered blocking state"
"vmbr1: port 2 entered disabled state"
"vmbr1: port 2 entered forwarding state"
"vmbr1: the hash_elasticity option has been deprecated and is always 16"
 
It looks like all your ethernet interfaces are gone.
Either they are not detected anymore, for example with a newer kernel, like @spirit said, or there is some sort of an physical problem.

Do you have any (not only NIC-related!) PCIe-passthrough configured? Device-binding? Driver-blacklisting?

What exactly are those four ethernet interfaces (eno[1-4])? Onboard? LOM? Quad-Port-Addon-Card? Several Addon-Cards?
What are their exact brand and model?

Try booting with an older kernel and see with the commands above, if the ethernet interfaces come back.
If not, you could try a Live-Linux-ISO to see if your NICs are recognized there.
