ip route show
default via 192.168.4.1 dev ens192 onlink
192.168.4.0/24 dev ens192 proto kernel scope link src 192.168.4.12

BINGO!

192.168.4.0/24 is wrong, should say 192.168.4.0/22

Do you know why?

In /etc/network/interfaces looks correct:

allow-hotplug ens192
iface ens192 inet static
address 192.168.4.12
mask 255.255.252.0
gateway 192.168.4.1
dns-nameservers 192.168.4.3
dns-search mydomain.co.uk
