NOTE

Sometimes when proxmox reboot it does change the network interface Ex: from enp4s0 to enp3s0 so the network will stop working completely.

How to fix it:

  • Check that etc/network/interfaces do not contains errors by using ifup vmbr0 on the command line
  • Check network interfaces with ls /sys/class/net, it should give you all the current interfaces. Update the file etc/network/interfaces with the new bridge ex: enp3s0
  • Another command could be hwinfo --short --network
