I can't test because I don't know of an address displaying this message, but is that message coming in the ON SNOTICE event or something besides ON DISCONNECT? If not, i'd see what kind of message is shown by a @debug window. /help /debug

The purpose of the "try next server" is when the attempt to connect fails, but if it allows you to connect but then immediately disconnects you, then it will keep connecting to the server it successfully connected to in the first place.
