It has found 200.166.132.11, which is one of the nameservers for jfce.gov.br

And 200.166.132.10 is the other one, so looks like a problem between
your server and those two.  Can you query them directly, eg

  dig @200.166.132.10 www.jfce.gov.br. a +norec

I can from here.  Ah, but not if I use port 53 as the query-source,
so could be their firewall is refusing queries from port 53.
