If this happens again, you could call "M-x
tramp-cleanup-all-buffers". It clears all connections *and* kills all
buffers related to a remote file.

For further analysis, I would need the Tramp debug buffer. If you set
permanently tramp-verbose to 6, relevant information are traced. Well,
at least as long Tramp is mulish ...

Again, it is not clear what caused the problem. In order to get Tramp
improved, I count on users sending the traces.

Well, Emacs 26 is out, and the integrated Tramp shall behave
better. Yes, this is my hope all the years ...

Best regards, Michael.
