本地计算机有一个使用 SSH 克隆的 bitbucket 存储库。Windows 11 更新后，git push/pull 等导致错误“kex 协议错误：类型 30 序列 1“。经过几个小时的调试，我还是找不到可行的解决方案。
我做了什么
- 更新了 git scm
- 更新了 putty
- 将 Git bash ssh 客户端更改为 putty
- 改变了 putty 中 diffie-hellman 密钥交换优先级的顺序
- 将 diffie-hellman-group14-sha1 添加到 sshd_config 文件/添加了
- 尝试过 putty、powershell、visual studio code 等
- 生成新的 ssh 密钥并将其添加到 ssh 代理
似乎什么都没起作用。我遗漏了什么吗？或者有什么可以做的吗？请帮忙
更新-我的 sshd_config 文件的内容

解决方案
经过这么多事情，操作系统更新和软件更改，该问题与网络的 IP 地址有关。 IPv4 中一切正常。上述错误仅发生在 IPv6 网络上。这可能与 bitbucket 对其 SSH 密钥交换的实现有关。希望这对某些人有帮助
