weird ADCH++ problem

[dodzy]

i've setup a secure hub (adcs), and i can connect to it, no problem, but when i ask others to try to connect to it, they cant connect, they're stuck at "connected" msg and the userlist doesn't load etc, when i run the hub in debug mode its like the hub doesn't respond to the connection, netstat -tulnap gives me that the connection is ESTABLISHED so it must be adch++'s fault :S

nope it can be that they haven't configured their client proper.. or that its old.
