社内プロキシ内からAWSを利用しようとした際に下記エラーが出て困っております。  
ネットを調べたところ環境変数にプロキシを設定すれば大丈夫とのことですが、  
それでは解決されなかったため質問しております。

解決策をご教示願えませんでしょうか。

<環境>

windows 7

<実行文>

```

    aws ec2 describe-instances --debug
    
```

```

事前にプロキシの設定はしています。

```

    set HTTP_PROXY=http://proxy.xxxxxx.co.jp:8080
    set HTTPS_PROXY=http://proxy.xxxxxx.co.jp:8080
    
```

よろしくお願い致します。

question
aws
AWS-CLI利用に伴うエラー
`region = us-west-2a` ではなく `region = us-west-2` (AZなし)とするのではないでしょうか。
