Ruby on rails 4 轨道4+；无法使用NGINX在AWS服务器上上载APK文件

在我的Rails应用程序中，我可以在本地上传APK文件，存储位置是S3。但我在AWS服务器上尝试了同样的东西，让代码生效。无法上载该文件

对于同一条记录，缩略图和截图可以成功上传，但对于APK文件，它执行整个过程，但在页面重新加载后，它不存储记录

我在想，NGINX设置有问题。 NGINX配置文件：-

user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
  worker_connections 768;
  # multi_accept on;
}

http {
##
# Basic Settings

sendfile on;

client_max_body_size 300M;
client_body_in_file_only clean;
client_body_buffer_size 32K;
# server_tokens off;

# server_names_hash_bucket_size 64;
# server_name_in_redirect off;

include /etc/nginx/mime.types;
default_type application/octet-stream;

  gzip on;
  gzip_disable "msie6";

  # gzip_vary on;

  # gzip_comp_level 6;
  # gzip_buffers 16 8k;
  # gzip_http_version 1.1;
  # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

  ##
  # Phusion Passenger config
  ##
  # Uncomment it if you installed passenger or passenger-enterprise
  ##

  passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
  passenger_ruby /usr/bin/passenger_free_ruby;

  ##
  # Virtual Host Configs
  ##

  include /etc/nginx/conf.d/*.conf;
  include /etc/nginx/sites-enabled/*;
}

没有办法解决它
