[SOLVED] netdev_configure_server_empty: 1240 Invalid argument - Custom loopback device names not supported

Yesterday I executed the following inside a container because the private networking of hetzner only supports an mtu of 1400:

ip link set mtu 1400 dev eth0

Now if I create a new lxc container or restart an existing one, it fails to start with the following message:

netdev_configure_server_empty: 1240 Invalid argument - Custom loopback device names not supported
lxc_create_network_priv: 3413 Invalid argument - Failed to create network device
lxc_spawn: 1837 Failed to create the network
__lxc_start: 2068 Failed to spawn container "104"
TASK ERROR: startup for container '104' failed

I can't seem to find any information on this error, anyone here have a clue?

Backupped containers, did a full reinstall and everything works again.
