Yes, the debug buffer tells us more.

Well, the discussion about the PIN isn't visible, likely in the
suppressed traces. This might result in problems in the future.

What is the shell output, if you call

--8<---------------cut here---------------start------------->8---
# ssh -o ControlMaster=auto -o ControlPath=tramp.%C -o ControlPersist=no -e none 128.40.123.56
--8<---------------cut here---------------end--------------->8---

However,

This tells us the current truth. Your remote prompt contains color
escape sequences, and Tramp dislikes them. Pls consult the Tramp manual
how to suppress them.
