without debug logs from both the client and server in this situation, it's
not really possible to say what is going on.

Bear in mind that the Portable OpenSSH project and the Windows OpenSSH
project are separate. They use our code, but do a number of things quite
differently so if you suspect a problem in their code then they are the ones
to contact (e.g. via a github issue).
