I have tried to look in different forums before posting here but sadly I failed .
I have fixed the problem, I added allow-query { any; }; in named.conf.options and called my ISP to check if port 53 is blocked (there was a bad port forwarding from my router). Sorry for disturbing you can close the threat.
