Ok, that's useful. It is not the 502 error, but it is something.

This is "the client (curl) does not like the fact that the server is
presenting a self-signed certificate".

One way to tell the client to accept the certificate is to add " -k"
to the command line.

However, the older nginx log entry...

suggests that at that time, nginx was unable to connect to gunicorn.

That is usually a configuration (access control) problem outside of
nginx's control; if that problem persists, you may want to check the
gunicorn config or logs to see what it thinks is happening.

Good luck with it,
