Here, instead of using a rewrite, try with

         proxy_pass https://remote.server.com/remote-proxy/

I'm not sure to understand what you are trying to do.
But try with:

        set $authorization upstream_http_authorization;
        set $some_other upstream_http_some_other_header;

in the / location

and:

        proxy_set_header Authorization $authorization;
        proxy_set_header Some-Other-Header $some_other;

in the remote-proxy location


However I'm rather sure that this will not work :).
