VS Code 无法从 mac 连接到远程 Ubuntu 机器答案

【问题标题】：VS Code is not able to connect to Remote Ubuntu machine from macVS Code 无法从 mac 连接到远程 Ubuntu 机器
【发布时间】：2021-01-25 19:46:11
【问题描述】：

我正在使用 Remote-SSH 扩展并尝试从运行在 macbook 中的 vscode 连接到 ubuntu 服务器

VSCode 显示错误消息“无法获取远程环境”

并显示消息“无法连接到远程扩展主机服务器（错误：已达到时间限制）”

我已按照远程 ssh 故障排除步骤中的建议将连接超时时间增加到 60 秒，但仍然遇到此问题。

当我在 vscode 中启动会话时，我可以看到以下日志，

717b5473e20d: running
