Here is the main problem:

dig maktabkhooneh.info +trace

works perfectly fine and returns the right answer.

dig maktabkhooneh.info

(without +trace) returns:

; <<>> DiG 9.8.1-P1 <<>> maktabkhooneh.info

;; global options: +cmd

;; Got answer:

;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 58716

;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

What could be the reason? I was reading this. Is it the only possible reason that I changed domain data 12hrs ago? Isn't there any other possible reason for SERVFAIL?

extra info:

I have two BIND servers working on 168.144.251.73 (master) and 168.144.92.50 (slave).

and on the master I have:

In my case was a problem related to /etc/named.conf file. I could resolve this with the previous answer from Sandman and googling the way to fix a corrupted named.conf in cpanel. I had to access to shell console and type the following commands:

for backup the file

mv /etc/named.conf /etc/named.conf.bak

for rebuild the file

/usr/local/cpanel/scripts/rebuilddnsconfig

for restart the named service

/etc/init.d/named restart
