In general, he solved this problem himself. In my case it is done like this:

location ~* ^.*\/(?<pschema>.*)?:\/\/(?<phost>[a-z0-9\.\-]*)\/(.*)\.(eot|otf|ttf|woff|svg|css|js|png|jpg|gif)$ {
                rewrite ^.*\/(?<pschema>.*)?:\/\/(?<phost>[a-z0-9\.\-]*)(?<ppath>.*)$ $ppath break;
                proxy_pass $pschema://$phost;
                proxy_set_header Host $phost;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_redirect off;
                break;
        }
