使用nginx反向代理到webman后，下载文件失败

问题描述

使用webman做服务端远程下载，客户端用php去请求这个接口下载远程的文件，没有下载完就报错了
客户端使用IP+端口方式进行请求下载就没问题，使用nginx代理下载就会被断开

程序代码

服务端代码

$data = json_decode($data, true);
$file = base_path("/version/{$data['version_name']}.zip");
if (!file_exists($file)) {
return $this->fail("{$data['version_name']} 版本更新包不存在");
}
// 返回文件
return response()->file($file);
