Thanks for the suggestions. See my comments, below, please.

The original report for #3383 was given by me. Presently, I force use
of the external command for SSH as a workaround. This solution resolves
the problem, as evidenced by my success when invoking from the command
line. The problem I am describing now seems to me not part of the issue
reported in #3383.

Issue #3295 is in regard to an attempt to connect without a password,
and as such, is also not closely related. I am using password
authentication, and I have tried enough times that to be clear that a
wrong password is not the problem.

Issue #3300 too seems a poor match. It was reported under Windows, and
shows a dialog box with a message about failed authentication. It is
also has been reported resolved in the version that I have tested,
without success. Issue #3372 is reported a duplicate.

The verbose output seems to show nothing rather helpful (see below). I
checked the values for protocol, username, and password. As I
indicated, of course, I have been successful using the same values in
an invocation through command line.
