I think you are saying that you want nginx to be a "plain" tcp-forwarder
in this case.

(I'm not certain *why* that matters here, but that's ok; I don't need
to understand it ;-) .)

Does http://nginx.org/en/docs/stream/ngx_stream_proxy_module.html work
for you?

Something like

==
    stream {
        server {
            listen nginx-ip:443;
            proxy_pass traefik-ip:443;
        }
    }
==

(If you have a stream listener on an IP:port, you cannot also have a
http listener on that same IP:port.)

Your picture also shows some blue lines on the left-hand
side, so it may be that you also want something like
http://nginx.org/en/docs/stream/ngx_stream_ssl_preread_module.html,
to choose which "upstream" to proxy_pass to, depending on the server
name presented in the SSL connection to nginx.

Cheers,
