nginx - nginx 書き換え 404 エラー

Question

どのように機能するか

1. フロントエンドの開始ページはhttp://server/apex/- デッド ページです
2. 作業ページにリダイレクトし、to /apex/f?p=100:4:0::NO:::
3. きれいな URL タイプを作る http://server/apex/4/0/NO

location / {

   proxy_pass http://127.0.0.1:8080;
    include /etc/nginx/reverse_proxy.conf;
    rewrite ^/$ /apex/f?p=100:4:0::NO:::? permanent;
       }

location  /apex {
    proxy_pass http://127.0.0.1:8080;
    include /etc/nginx/reverse_proxy.conf;

    if ($args ~ "p=100:(.*):(.*)::(.*):::") {
                  set $args $1/$2/$3/$4;
                  rewrite ^/[a-z]+/.+ /apex/$args?;
                              }
        }

nginx からのログ - access.log "

GET / HTTP/1.1" 301 178 "-"
"GET /apex/f?p=100:4:0::NO::: HTTP/1.1" 404 5

私は何を間違っていますか？
