"Your system's primary IP address appears to have changed from..."

Hello there.

I am using Virtualmin (on top of Centos 7) in a virtual environment, who ever knows, Hetzner's one which all the VPSes has an internal IP of 172.31.1.100.

Virtualmin gives me the warning:

! Your system's primary IP address appears to have changed from 78.x.x.x to 172.31.1.100. Virtual servers using the old address may be unreachable or serve the wrong web content.

Is there a way to "by pass" this warning ? Or just ignore it ?

Because if I hit the "Update incorrect IP address" button if messes everything and apache vhosts stop working.
