I have previously reported this behavior, and not seen a fix, it used to work.
The problem is running xauth under the covers hangs.
If you add -v -v -v to your line above, you'll see it hang like:
debug2: x11_get_proto: /usr/X11R6/bin/xauth -f
/tmp/ssh-c96kVgf686/xauthfile generate 127.0.0.1:0.0
MIT-MAGIC-COOKIE-1 untrusted timeout 1200 2>/dev/null
If you remove the X forwarding switch (i.e., not use -X) you should be
able to login.
If you kill the X server and/or kill the hung xauth process, an
'empty' ssh Window (non-X) will appear, indicating to me that for some
reason, xauth is looking for input from the console vs. stdin.
As a work around, you can manually reverse forward the display, something like:
ssh -R 6001:localhost:6000 user AT system
then manually setting your display, in the above case:
export DISPLAY=:1
Manually picking a port as above can interfere or fail if it is
already in use, using the -X (or -Y) enlists the sshd on the target to
find a free port.
