重现步骤：

1. 登陆公司的VPN (代码在公司内网)
2. 重新生成sshkey: 执行命令 ssh-keygen
3. gitlab上添加新的sshkey: 执行 open ~/.ssh/id_rsa.pub 获取
4. git cl xxxx 拉代码 // 报错了

根据报错信息尝试的解决办法：

一、WARNING: POSSIBLE DNS SPOOFING DETECTED!

dns使用的google 8.8.8.8, 8.8.4.4，排除DNS问题

二、The ECDSA host key for gitlab.xxxxxx-inc.com has changed,

根据错误信息找到 https://www.jianshu.com/p/04a... 资料。
执行步骤

• 清空.ssh内容 // 这一步是关键
• 执行: ssh-keygen 重新生成 sshKey,再添加到gitlab中
• 通过 git cl [e-mail]:xxxx_organization/xxxx-data.git 拉取代码成功
