中国移动云盘

Describe the bug / 问题描述

本地文件复制到移动云盘，小于8G的文件都没问题，超过8G的就会报400错误（看截图），我的移动云盘是会员，可以上传超过8G的文件，我试了PC安装移动云盘客户端，拖进去上传是成功的（非秒传）

Reproduction / 复现链接

随便找个8g以上不会秒传的mp4文件，我这里是12g的，alist docker做好本地映射，用本地文件复制的方式上传到移动云盘，在上传到70%,80%时会报400错误，然后重新上传，如此反复截图中的速度300多m是报错时临时性的，实际不是，实际上传是8m左右另外，试了v3.43.0以及后面所有正式版本都不行

再反馈一个最新的3.50.0的bug，还是中国移动云盘，用流舟文件挂载alist的webdav查看移动云盘的文件，中文显示乱码，之前的版本都是正常的，nplayer试了也是显示乱码

配置文件如上没有变化

我也遇到这个问题了，上传大文件时alist内存占用特别高，哪怕使用stream上传也一样
