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)
