Edit the network file and add static server addresses. (It is more stable for server)

sudo vi /etc/network/interfaces

# network interface LAN Access
allow-hotplug enx24f5a2f22d02
iface enx24f5a2f22d02 inet static
address 10.0.0.9
netmask 255.255.255.0
gateway 10.0.0.1
dns-nameservers 10.0.0.2

# network interface WLAN Access
allow-hotplug enp7s0
iface enp7s0 inet static
address 10.1.1.1
netmask 255.255.255.0
dns-nameservers 10.0.0.2

Deactive the Networkmanager which only starts once you are logged into the desktop and start the old and more stable networking script for servers.

sudo systemctl stop NetworkManager.service && sudo systemctl disable NetworkManager.service && sudo systemctl restart networking
