Capistrano：网络无法访问错误，但可以通过 ssh 连接到服务器

Question

我正在使用新服务器设置 Capistrano 3，以便我可以部署 Rails 应用程序，但目前卡住了。每当我运行任何 cap production 任务时，都会发生这种情况：

$ cap production deploy:setup
cap aborted!
Errno::ENETUNREACH: Network is unreachable - connect(2) for [IPv6addresshere]:22

我花了几个小时试图解决这个问题，但不确定发生了什么。我可以作为 Capistrano 使用的同一用户使用 ssh 而无需密码，因为我有授权密钥设置。此外，在远程服务器上，我可以 ssh git@github.com 正常，因为我配置了部署密钥。

有什么建议吗？

我发现我已经正确配置了我的 deploy.rb 文件但忽略了更新 deploy/production.rb，该文件的用户配置为 deploy@example.com。因此，在主配置文件中的部署步骤运行之后，它会根据生产设置尝试相同的步骤，但无法获得 SSH 连接。这毕竟是一件简单的事情！感谢评论的人。
