Sounds like you're banned for some reason. What nick are you using to connect?
PS. Seems some prat was spamming the wiki, ought to be fixed now. You do seem to have got stunnel set up correctly though else it wouldn't have even made the initial connection to the hub
Has the problem been solved?? Are you not receiving any messages on the side by any chance? Perhaps from Dogtanian? It usually should at least say if u've got banned.. it just seems to close ur connection, which seems to suggest either an auto kick or a bad connection.
