I presume that the 404 comes from your upstream server. Use
proxy_set_header to set whatever header values that upstream needs,
to handle the request.

I suspect that "proxy_set_header Host $1;" is what you want -- or to
have no proxy_set_header directives at all so that the default applies.

It all works fine for me.

Can you provide evidence of where it fails to do what you expect?

Perhaps tcpdump the traffic, and see what does nginx send to upstream? If
it is the expected correct client request, then you should check what
the upstream does with a similar request that you make using, say, curl.

Provide a specific example of what exactly you do, ideally using "curl",
and what response you get, and what response you expect. That's the best
way of making it easier for someone else to help.
