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：  
[whole log.txt](https://meta.discourse.org/uploads/short-url/t21rdEbZyeaILpFgfVSuRwXDug3.txt) (18.3 KB)

看起来重建失败了，我运行了 ./discourse-doctor，显示：

```plaintext
==================== SERIOUS PROBLEM!!!! ====================
