启用S3存储时无法上传头像（文件已存在，但仍失败）

[Michaël (Michaël Joseph)]

@DigneZzZ

大家好，

我在 Discourse + S3 存储方面遇到一个奇怪的问题。

上传头像时，我会收到类似下面的错误——尽管文件确实存在于 S3 存储桶中，并且可以通过有效的 s3_cdn_url 访问。

帖子和附件的上传工作正常。唯一失败的是用户头像上传。

这是容器的 S3 URL

//gig.s3.ru-1.storage.selcloud.ru/original/1X/fd42dfa3362b66090450f2ae40f0917193fcd355.jpeg

图像可在以下 URL 访问：

https://s3.gig.ovh/original/1X/fd42dfa3362b66090450f2ae40f0917193fcd355.jpeg

附加信息

• Discourse 版本：(最新稳定版)
• 使用外部 S3 兼容存储 (enable_s3_uploads = true)
• s3_cdn_url 已正确配置并使用
• CDN URL 成功返回文件
• 文件已确认存在于预期的 S3 位置
• 其他上传（图片、附件等）工作正常
• 错误仅发生在用户头像

问题

为什么 Discourse 在文件存在且可以通过正确的 CDN URL 访问的情况下，却无法检索文件以进行头像处理？

头像处理（例如 get_optimized_image）是否有任何特殊配置错误或缓存问题？

任何建议或见解都将不胜感激！

谢谢

您好——您最终解决这个问题了吗？

我在 Discourse + S3（仅头像）上也遇到了完全相同的症状：
Could not find file in the store located at url: //<bucket>.s3.dualstack.<region>.amazonaws.com/original/1X/<hash>.jpeg

我的设置的一些细节，以防与您的相似：

• enable_s3_uploads = true，对象位于 original/* 和 optimized/*（没有 uploads/default 前缀）

• 通过 CloudFront (OAC) 访问，存储桶本身是私有的

• 对象确实存在于该键下；CDN URL 有效

• 错误仅发生在头像处理

• (可能的症结) 上传使用 SSE-KMS 加密

如果您找到了根本原因或修复方法（策略更改、KMS 权限、存储桶路径对齐等），能否分享一下有效的方法？谢谢！
