sorry for bothering u, i find the problem, my 53 port was bind to another process
and pdns couldn't connect to it, in order to start
if somebody else have the same problem, just use
first check if u have virb0, then disable it to stop binding dns ports
# su
# ifconfig -a
# systemctl stop libvirtd.service
# systemctl disable libvirtd.service
and if its this didnt helped u, u can check the binded ports by
# sudo netstat -lntup
then if 53 was binded, u can unbind it with
# fuser -k 53/tcp
# fuser -k 53/udp
