"xauth generate" _replaces_ the cookie in the specified xauthority
file with an untrusted one.  That error message is the one you get if
you _already_ have an untrusted cookie in your xauthority file - ie,
if you run "xauth generate" for the second time without running the
"cp" again.

If you ran xauth generate without the -f option then I'm afraid you
have busticated your session.

Of course it may be that that error message is also the one you get if
a fixed server rejects your big timeout, but that should be easy
enough to test ...
