Stock nginx does not speak proxy-http to a proxy server.

Only if you arrange for the code to do it be written.

If you choose to write it fully, it might be welcomed into stock nginx.

Your proxy is correct to do so.

It just expects a protocol that nginx does not speak.

Use something that can be a proxy client, and use it instead of (or as
well as) nginx.

Or, since nginx is a reverse proxy, and you only reverse proxy for things
you control, change your policy so that nginx can talk to your external
web server without going through the proxy.

I don't think that there is a "good" answer.
