irc.cuff-link.me resolves to 22.214.171.124 and 126.96.36.199 and 188.8.131.52[my.gshou.com]
Those are 3 different IP addresses to 3 different computer machines. 184.108.40.206 and 220.127.116.11 have an IRC service on +6697, but 18.104.22.168 does not.
As mIRC rotates through these servers, it's going to fail when attempting 22.214.171.124, until it cycles to one of the other two.
