Yes, it's in the archives. The reason is the .Xauthority
entries that X11 writes, which can checked with
xauth list
After a network change, the new hostname (obtained by whatever means) will
not match the entries in the .Xauthority file, which leads to the refused
connection.
One solution posted in the archives was to use
defaults write com.apple.x11 no_auth true
I understand this will prevent X from listening to tcp connections --
indeed, they don't show up on a netstat -na listing. As long as X
connections are handled through ssh forwarding it should be fine, I think.
Otherwise, use
defaults write com.apple.x11 nolisten_tcp false
