I recently moved my virtual vpn router to another machine, with the result that the ethernet interface changed. Everything was connecting, but vpnfailsafe kept kicking everything off.
I recently moved my Pi-Hole virtual machine to a different back-end, with the result that DNS resolutions started failing across the board. Upon closer inspection, I noticed that Pi-Hole had not realized that the network interface had changed, from enp1s17 to enp1s0, which you can see in the web management page tab: settings / system. The result was that it could not communicate to the outside world.
