Unfortunately if the tramp traces aren't available I think there's nothing
else I can do to help you. I would just be sure to double check everything
to make sure you're typing everything accurately etc. I haven't seen the
TRAMP debug facilities fail like that and that's pretty battle-tested
software so I think it's likely that you're simply mistyping something.

Good luck!
