No Web gui and random connection reset by peer

I recently updated one of my 2 proxmox servers and now trying to pull up the GUI in Chrome I get:
This site can't be reached
192.168.1.131 refused to connect

​

If I try to SSH, I get "Network error: Connection refused"

If I go to server 2's GUI (the working one) and then select server 1 and bring up the shell, it works for a random amount of time. Then I eventually get:

Read from remote host 192.168.1.131: Connection reset by peer
Connection to 192.168.1.131 closed.
client_loop: send disconnect: Broken pipe

There is an LXC running in server 1 and I can connect to it.

My replication jobs from server 2 to server 1 are randomly failing with this emailed message:
Replication job '100-0' with target 'proxmox1' and schedule '*/1:00' failed!

Last successful sync: 2026-05-28 10:00:21
Next sync try: ERROR
Failure count: 1

Error:

Thanks for any help!
 
On both nodes: How does your network configuration look like?

Code: 
cat /etc/network/interfaces
ip a
ip r

What NIC models do you have?

Code: 
lspci -nnk

For node 2 (the working node) - this has an Intel e1000e NIC and I had to disable NIC offloading (I implemented this fix https://gist.github.com/crypt0rr/60aaabd4a5c29a256b4f276122765237)

Hello @bubblegoose, welcome to the forum.

There is one issue we should address first: the format of the data you provided is very difficult to read. Forum members, myself included, would greatly appreciate it if you could edit your post and use CODE tags (available in the editor toolbar) when sharing logs, configurations, command outputs, and similar technical information.

Additionally, the network configuration from the “working” node appears to be missing the actual IP configuration. Perhaps those settings are defined in another file that was not included.

Regarding your main issue, the symptoms are very consistent with a duplicate IP scenario. I would suggest dumping and comparing the ARP tables across all involved hosts. If you find inconsistencies or MAC/IP conflicts, resolve those first.

Cheers
