I removed the last 3 lines bellows:

BEFORE:

```
auto lo
iface lo inet loopback
auto enp4s0
iface enp4s0 inet static
        address __IP___
        netmask 255.255.255.248
        gateway __IP___

```

AFTER:

```
auto lo
iface lo inet loopback
auto enp4s0
iface enp4s0 inet static

```

Then I hit a **reboot** action and cannot start + access server anymore.

* How can I do now?
* Can I still save my data?

Supporter gave me a KVM account to access KVM and I see a Server Manager, I don't know how to use it to connect to my server in the data center while my server is offline.
