These logs do seem to indicate that the tls-negotiation part of things
is working ok, so the error message in the Subject: seems to no longer
be an issue?

The fact that your upstream is using WWW-Authenticate: Negotiate and
RDG_OUT_DATA makes me suspect that it may be using some Microsoft-specific
non-standard-HTTP things that either may notwork through a reverse proxy,
or may not work through nginx.

I don't have a better answer for you; if you want to continue trying,
are you able to re-create the client / nginx / upstream server setup
that worked in the past? Then maybe change only one piece at a time to
see where the first breakage happens?

Good luck with it,
