```IllegalStateException``` while running cloudcatcher and TLCO

Details

This happened while I was AFK on switchcraft. The following files may be relevant:

cloud.lua startup.lua prep.lua lib/homura.lua lib/hub.lua

I suspect this is just an internal netty error, but we should do a better job of what error we expose to the user.
