That's strange indeed, as averytickets.com is in DNS and I can browse to the empty directory (I am assuming you can too?). If the domain is new, it is possible DNS has not completely updated,and that I can see it in DNS and you can't (yet).
If you can see it in DNS, and you are sure you have no firewall issues, those setting should work.
If I ping "ftp.averytickets.com", I get response from "apache2-argon.conker.dreamhost.com (18.104.22.168)", so I don't think actually connecting to the domain should be a problem.
Begging the obvious, you are sure there is no user/pass problem?
