VSCode 连接不上远程服务器的解决方法
省流：打开 C:\Users\AJohn\.ssh\ 路径，直接删除 known_hosts 文件。
正常用了一段时间，突然 VSCode 连接不上远程服务器了，疯狂重连 + 重启服务器 + 重装服务器系统皆未解决，最后发现是本地存储密钥不一致导致的。
使用 VSCode 连接远程服务器 ubuntu@36.103.199.74 出现下面报错：

[09:53:32.086] ------但是使用 xshell 可以连上远程服务器
尝试在远程服务器上清除 VSCode 缓存
使用 ls -a 查看所有文件
使用 rm -r .vscode-server 清除 VSCode 缓存文件 .vscode-server
但是没什么用，此路不通（
打开命令行终端，手动测试与远程服务器的连接：
ssh ubuntu@36.103.199.74
连接失败，报错提示目标主机的 SSH 主机密钥与之前存储在本地 known_hosts 文件中的密钥不一致。
因此，打开 C:\Users\AJohn\.ssh\known_hosts 文件，找到第 15 行并删除该行（也可以直接删除 known_hosts 文件）。
再次使用 VSCode 连接服务器，已经可以连上了。好耶ヾ(✿ﾟ▽ﾟ)ノ！
