You did the classic mistake - assuming what the problem is and then trying to
find a solution for that problem.
You should start with just describing what you see - and the logs you sent
indicate that the named is unable to communicate on port 53. This indicates
that your network (firewall on the server, firewall at the provider) might be
blocking DNS queries to the outside world. You should diagnose that - try
sending DNS queries to those addresses by hand and look what’s happening on the
wire (tcpdump, wireshark, etc. are your friends).

You are right !
There was indeed a limitation on outbound traffic on port 53 in the network.
It is now working good.
Thanks,
Julien
