no subnet declaration & not configured to listened on any interfaces error message trouble

[LOCHET Charles]

We have 2 Dhcp server, dhcp3 service former debian, then changing
of virtualizing server, I have to reinstall them on new esxi virtualizing servers,
so did install debian 10 and isc dhcp server, copie dhcpd.conf config file and adapt it,
verify it with dhcpd -t dhcpd.conf got not error,
so start it and got error message:

no subnet declaration for start (no ipv4 adresses)

not configured to listen on any interfaces!

I then checked /etc/default/isc-dhcp-server    and   /etc/network/interface   files
which looked ok.
I had been advised to start with simpler dhcp.conf files to start and add bit by bit areas…
But I always get the same error message whatever subnet declration I have inside my config file.

I don’t understand what happens or what to do now… looks like what ever the dhcpd.conf file is, I get same error
message, is there any other config file I don’t know about ? or anything missing ?

server is at 192.134.130.43 and config files are such:
