there is nobody in particular, but a range of people. for example when A and B tries joins the same game and we start it, one of them them is always "kicked" out to the main screen of the program. If (one) either A or B does not join the game, everything works perfect. we all have the same version of the game installed and the cncnet 5 works fine for all. Last night when C joined the game, A and B (random examples) were not able to play anymore, but for me and others (3 people) it loaded just fine. not sure what the problem is, but I believe that it is something from cncnet 5...
if it helps, we all know each other, we are friends, and we want to play between us.
