Bind9 not working reverse zone

Hello everybody, I recently change my OS to debian jessie and I can't make the server work properly.
/etc/resolv.conf
================
nameserver xxx.yyy.zzz.2
nameserver 8.8.8.8
nameserver 8.8.4.4

======
/hosts

//JUJUYTEL

zone "midominio.com" IN {
type master;
file "/etc/bind/directa/midominio.com1";
allow-query { any; };
};

//reversa
zone "zzz.yyy.xxx.IN-ADDR.ARPA" {
type master;

allow-query { any; };
};

allow-query { any; };
};

//MAIL

allow-query { any; };
};

I get this error
============
nslookup

** server can't find 2.zzz.yyy.xxx.in-addr.arpa: SERVFAIL

I hope someone can guide me with this.
Best regards.
