Anyone over here familiar with the Ubuntu Server LTS? I’ve been running multiple OSes on virtual box for a long time. Recently, I started having a problem with NAT (set on my 2nd adaptor), even though setting those configuration correctly, still getting problem. I also use Host-Only Adapter too, I communicate with other vm's on my own pc. My network interfaces, enp0s3 (enables always) and enp0s8 (disable from few days). Any clue why this error happening?
