当我尝试使用 PowerShell 或 Cygwin 从我的 PS 连接到托管我的 Wordpress 网站（Bitnami）的 AWS 时，遇到以下问题。
（我只是想通过这种方式或使用 Putty 登录到服务器，如下所述（[LINK][1]油灰抛出错误“使用用户名 bitnami。服务器拒绝我们的密钥。没有可用的受支持的身份验证方法。服务器发送了公钥“)
我目前尝试过的方法是：我执行以下任一命令或同时执行以下两个命令...
chmod 600 <key-pair-from-aws>.pem
chmod 400 <key-pair-from-aws>.pem
（当我登录到 ec2 实例时，在“密钥对”部分下我看到了一个条目，但我无法下载它。这就是我生成新密钥对的原因，这就是我在下面的命令中使用的文件。）
然后我输入以下命令...
ssh bitnami@<public-ip-address> -i <key-pair-from-aws>.pem
...我收到以下错误：
'(key-pair-from-aws).pem' 的权限太开放。要求您的私钥文件不能被其他人访问。此私钥将被忽略。加载密钥“.pem”：权限错误 bitnami@(public-ip-address)：权限被拒绝 (publickey)。
现在，如果我在 PC 上选择文件“属性 -> 安全 -> 高级 -> 禁用继承”，然后删除除我的用户之外的每个用户，然后执行相同的命令...
ssh bitnami@<public-ip-address> -i <key-pair-from-aws>.pem
...我收到以下错误：
bitnami@<public-ip-address>: Permission denied (publickey).
我在这里卡住了，因为我不知道如何继续。在 Stackoverflow 和 Google 上搜索后，我找不到任何可以帮助我解决这个问题的东西。
有人能帮忙提供具体的分步说明吗？谢谢！
更新：这是命令 $ ssh -v -i "pem-file-name.pem" bitnami@ 的结果
