[Bug] Nginx反代MinIO时无法访问

[MacMillan1225]

描述

我在 mcp-echarts 中配置了 MinIO 存储，并使用 Nginx + HTTPS 域名代理来访问 MinIO S3 API。
直接访问 MinIO API 正常，但通过代理时 mcp-echarts 上传失败，并fallback到 Base64 输出。

---

环境信息

使用Cherry Studio最新版配置
如果使用本地的方式

MINIO_ENDPOINT=192.168.1.1
MINIO_PORT=19000
MINIO_USE_SSL=false
MINIO_ACCESS_KEY=***hidden***
MINIO_SECRET_KEY=***hidden***
MINIO_BUCKET_NAME=mcp-echarts

可以正确访问

---

配置摘要

反代版
.env 中 MinIO 相关配置如下：

MINIO_ENDPOINT=<my-minio-domain.com>
MINIO_PORT=443
MINIO_USE_SSL=true
MINIO_ACCESS_KEY=***hidden***
MINIO_SECRET_KEY=***hidden***
MINIO_BUCKET_NAME=mcp-echarts

这个复现比较麻烦，可以用代码在你本地测试看看吗？

看起来像是端口问题导致，方便提供一下更加详细的配置信息吗，比如nginx的

抱歉，最近很忙没有时间测试，这边是我的配置信息：

部分内容已做脱敏处理：
域名替换 → example.com
绝对路径替换 → /path/to/...
证书路径替换 → /path/to/cert/...
内网端口替换 → PORT_PLACEHOLDER
日志路径替换 → /path/to/logs/...

补充一下，后来我自己使用了MINIO这个储存库，如果正确配置了的话，这个是能够调用它的API的，并且我这边写通过本地的方式上传之后也能够通过域名正常访问开放资源

好的，如果我们能够成功复习就会尽快解决~
