GitHub webhook 无法连接到 VPN 内的 Jenkins？

问题描述

我正在使用 Jenkins 和 GitHub Enterprise 设置持续集成。

到目前为止，我已经能够轻松地创建 Jenkins 项目并定期运行作业。

• Jenkins 正在使用 SSH 公钥/私钥对 GitHub 存储库进行身份验证和克隆。
• Jenkins 在我公司 VPN 网络内的 Linux 服务器上运行。

我的下一步是配置 Jenkins/GitHub，以便 GitHub 的每个 git push 都会触发 Jenkins 构建作业。我已经在 GitHub 上设置了提交后 webhook，并在我的 Jenkins 项目中启用了 GitHub hook trigger for GITScm polling 复选框。

但是，GitHub 无法连接到 Jenkins。

这是日志：
