我尝试按照以下说明重建应用程序：[更改 Discourse 实例的跟踪分支](https://meta.discourse.org/t/change-tracking-branch-for-your-discourse-instance/17014)，但在更新 app.yml 并重建容器时：

```plaintext
git pull
./launcher rebuild app

```

我遇到了致命错误，显示：

```plaintext

并且网站显示：

> # 502 Bad Gateway

我该如何解决？

完整的日志在这里：

看起来重建失败了，我运行了 ./discourse-doctor，显示：

```plaintext

您是否正在使用代理进行出站流量？它似乎无法正常工作。

```plaintext
fatal: unable to access 'https://github.com/discourse/discourse.git/': 
  Received HTTP code 503 from proxy after CONNECT

```

My server is in China mainland, I have doubt that whether it was influenced by the GFW, make the rebuild action can not get the branch on Github?

是的，我的服务器在中国大陆，更新总是很困难，默认操作无法从 Github 拉取 git
