Hi Christian

I would say you have a defective NIC… :frowning:

-> If possible, replace it.

My 2 cents

Change NIC or tune it (adapting command to your NIC):

I had the same issue yesterday on my Proxmox Host(s) and solved it also with:

ethtool -K enp0s25 tso off gro off gso off

network-nic-offloads

Edit:
for i in $(echo $(ifconfig | grep ^e | awk -F: ‘{print $1}’)); do ethtool -K $i tso off gro off gso off; done
