Looks like you are missing a suitable subnet declaration in your dhcpd.conf file for the network segment to which interface enp2s0 is attached.

Well that i know as it is stated on the error, but i have no idea how to fix it

The ip address on your network interface has to be within the subnet of DHCP addresses you aim to serve. With "subnet 192.168.0.0 netmask 255.255.255.0" you will need an interface with an ip address in 192.168.0.0/24 on it.

Ty it now works, but for some reason that i don't know the server doesn't share internet connection with clients, any idea why?
Obs: cat /proc/sys/net/ipv4/ip_forward returns 1
