我刚刚创建了一个 EC2 实例来托管我的 Django 项目，并且我正尝试通过 PuTTY 连接到该实例，因为我使用的是 Windows 10（公司 PC）。

由于服务器仅允许公钥身份验证，连接被阻止。请联系您的网络管理员。

我已经尝试过的：
- 安全组向全世界开放（所有流量）；
- 用户名正确；
- 密钥已从转换
.pem为.ppk - 转换的密钥是在 SSH > Auth 上设置的；
- 我处于一个开放的网络上，没有任何限制；
- 我也尝试过使用 mobaxterm（通过 GUI 和命令行）来使用
.pem原始文件 - 同样的错误；
我在想，尝试了不同的 SSH 工具后，这可能是一些 EC2 配置细节......
我在托管项目时遇到了这个问题。有人能指导我找到解决方案吗？
谢谢！
答案1
在 Google 上搜索该错误消息，前两个相关结果都声称问题是由于防火墙上的 SSH 检查造成的。
无法将公钥与 bitbucket cloud 一起使用在 community.atlassian.com
好的，搞定了。我们在边界网关处进行 ssl/ssh 检查，这似乎是导致问题的原因。禁用 ssh 检查，或为 bitbucket 的 ips 添加例外，我现在可以从我的 bitbucket 存储库推送和拉取。
所有实例的基于密钥的身份验证均已损坏 - 即使是新的 EC2 实例和新的密钥对在reddit.com上：
是否存在超激进的 MITM 防火墙/路由器来干扰 ssh 流量？
深度检查让我失望了……防火墙肯定是一个 MITM。
这可以解释这种行为。虽然服务器声称是“OpenSSH”（实际服务器可能是 OpenSSH），但 OpenSSH 没有任何错误消息，例如“由于服务器仅允许公钥认证，连接被阻止。请联系您的网络管理员”。一定是某个代表真实 OpenSSH 服务器的中间服务器/设备注入了错误消息。
