so... i am trying to make a dc++ hub software, but i have a little problem. when more people try to connect it says "connection refused" to some peoples... if i try to reconnect, it finally connects me after i retry a few times (sometimes one, sometimes 20)... i saw that the connection request event does not occur sometimes, even if the winsock is listening on that port!!! what can i do? i tried to listen on another port, and i had the same problem
