Ubuntu on virtualbox no internet connection

Trying to access the internet on a virtualbox VM with Ubuntu-20.04.1 LTS and a WiFi adapter.

The VM has 2 network adapters. NAT and host only with a host-only adapter with static IP address.

The netplan config looks like:

network:  ethernets:    enp0s3:            dhcp4: yes    enp0s8:            addresses: [192.168.56.3/24]            gateway4: 192.168.56.1            nameservers:                    addresses: [4.2.2.2, 8.8.8.8]  version: 2

and ip addr show says:

2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000    link/ether 08:00:27:dd:a6:04 brd ff:ff:ff:ff:ff:ff    inet 10.0.2.15/24 brd 10.0.2.255 scope global dynamic enp0s3       valid_lft 86264sec preferred_lft 86264sec    inet6 fe80::a00:27ff:fedd:a604/64 scope link       valid_lft forever preferred_lft forever3: enp0s8: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000    link/ether 08:00:27:0e:27:7d brd ff:ff:ff:ff:ff:ff    inet 192.168.56.3/24 brd 192.168.56.255 scope global enp0s8       valid_lft forever preferred_lft forever    inet6 fe80::a00:27ff:fe0e:277d/64 scope link       valid_lft forever preferred_lft forever

enp0s3 is assigned a 10.x.x.x address but still it doesn't work, whereas another VM which gets the same 10.x.x.x address does work.

What am I missing?
