url rewrite, nginx выдает 404 ошибки, ничего в журналах ошибок

ниже rewrite работает нормально:

rewrite ^/city/restaurants$ /city/listings/restaurants permanent;

но это не работает

rewrite ^/city/restaurants$ /city/listings/restaurants last;
rewrite ^/city/restaurants$ /city/listings/restaurants break;

что я делаю не так?

ниже всего серверного блока nginx

  server {
          listen 80 default backlog=1024;
