This is puzzling indeed.  The error messages clearly indicate that
there is an authentication problem, but I'm surprised it doesn't
happen from the command line.

Can you position the cursor somewhere inside the function and then do
M-x edebug-defun RET, then try to open another connection?  Then you
can single-step through the function using SPC to see what's
happening.  I suggest that you open another frame with the *tramp/nil
address@hidden buffer so that you can see what's happening inside that
buffer as you're stepping through the function.

An interesting thing would be which command exactly is executed by
Tramp -- start-process is the function of interest, here.  Maybe the
problem lies there, and changing the command that's executed by Tramp

Another possibility is that terminal or environment settings foil
Tramp's attempts.
A preposition is not a good thing to end a sentence with.
