I have this problem. The network was not loading
The network services does not load

So the get in into the console and found that:

[FAILED] Failed to start Raise network interfaces.
 See 'systemctl status networking.service' for details

I did the command and the service was not load:


Solved by changing file /etc/network/interfaces doing:

vi /etc/network/interfaces
from:

auto lo

to:

auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet dhcp

then reboot and everything was fine again

A network card is missing from your /etc/network/interfaces. Was the problem right after the installation or did it work before?

During the UCS installation the configuration of the network is done. Was a network card shown here for configuration?

Hello Pixel,

The problem was after the installation. It works fine for months but for some reason (that i don’t know) the VPS lost connections
