The problem is more simple.
The server might be protected by a firewall or packet filter.
The latter allowing only connections to IRC port 6667.
So any scans outgoing from iauth may not get any answers back at all, not
even a RST.
TCP timeout is 30 seconds by default as far as I remember.
On the other side, some users may also have filtering protections which
turns out to the same result.
