strange problem on hobbit client 🔗 link

I've installed hobbit server on my pc and 11 hobbit client in other server but only three of this send client data, the other are silent (work only the test of the server's services).
host file is similar for everyone, all are slack linux (4 with the same version of slack and kernel).
x.x.x.x  rtd  # NK:http nobbd memory  disk cpu ssh  mysql apache=http://www.rtd.it/server-status?auto http://www.rtd.it smtp pop3 ftp  nod32 pgsql  LARRD:*,apache:apache|apache2|apache3 NAME:"RTD srl (1)"
