我想这是因为你缺少 `DISCOURSE_CDN_URL`。我们的配置如下：

```plaintext
DISCOURSE_CDN_URL: 'https://d16zv78c963s69.cloudfront.net' # 指向服务器
DISCOURSE_S3_CDN_URL: 'https://community-cdn-prod.debtcollective.org' # 指向 S3 存储桶

```

样式表从服务器获取，因此使用 `DISCOURSE_CDN_URL`。JavaScript 文件上传到 S3 存储桶，并使用 `DISCOURSE_S3_CDN_URL`。@Falco 在这里向我解释了这一点。

The problem from the title of the OP is this: CSS come from the app and JS from S3. You need a CDN that is aware of where every single asset is coming from and can reach the necessary place or two CDNs. That is why we have two different settings after all.
