Bear in mind that in posting these detailed logfiles you have revealed
private keymaterial. You will need to re-generate it.

The only part of this output that has any meaning to me is
"ssl_upgrade_failure" (which is pretty generic unfortunately), and
"certify". Maybe there is a problem with verification? Are you using the
same certificates and keys that you used for the Java test? Have you
tried turning peer verification off, just as a test? See the details
about "verify_none" here:


Another test you can perform is to place an stunnel proxy in front of
the broker and see if you can connect through that with the .NET client.
This may aid in producing diagnostics about where the problem lies.
