Nginx + apache - throw apache directly?

Question

Nginx

There is a script that works perfectly on pure Apache. but in conjunction with enginks can not be made to work.
can I somehow throw Apache for the directory right away?
this did not work
location ~* ^.*/papka/.*$ {
proxy_pass http://127.0.0.1:9000;
proxy_buffering off;
}

502 Bad Gateway means that no one is listening on the given address on the given port. Either Apache is not running, or it is listening on a different port/address.
