Thank you so much for your immediate answer, I wanted know how did you check
as 212.93.192.4 configured only on UDP?

Assuming the IP addresses is correct something is filtering the TCP
connections. DNS uses *both* TCP and UDP. It is a myth that TCP is only
used for zone transfers. Properly configured nameservers answer on both TCP
and UDP. 212.93.192.4 only answers on UDP.
