Cockpit cannot refresh cache whilst offline

If you are an VPS (virtual private server) enthusiastic and your are running Cockpit in your Ubuntu server, maybe you face it this issue, so here the solution,

Create a fake network and restart!

How to

Create /etc/NetworkManager/conf.d/10-globally-managed-devices.conf with:

[keyfile]
 unmanaged-devices=none

Set up a fake network interface 🤷‍♂️

sudo nmcli con add type dummy con-name fake ifname fake0 ip4 1.2.3.4/24 gw4 1.2.3.1

And restart your server!

This is really annoying but it is as it is even you could find a explanation that says:

Ubuntu uses two different network stacks which don’t play so well together.
