Ruby 拒绝连接到s3存储

我正在尝试使用以下代码通过附件fu将文件上载到amazon s3存储：-

has_attachment :storage => :s3,
                 :content_type =>
['audio/mp3','audio/flac','audio/wav'],
                 :path_prefix => '#####',
                 :output_path => '######',
                 :processor => :none

但会出现以下错误：-

连接被拒绝-连接（2）

---

正如ruby所说，由于某种原因，您无法连接到s3服务器

使用

telnet

命令在服务器上进行一些连接测试

i、 e.

telnet s3.amazonaws.com 80
