@karlatemp 在 time out ，服务器网络没有问题 中说：

这就是你服务器网络不佳

额，腾讯云服务，之前一直好的，突然有问题，是进黑名单了吗？

有proxy的功能吗？

@rainchan 在 time out ，服务器网络没有问题 中说：

网络问题，换一个服务器试试看

本地测试了一下，正常的

@yoonching 测试了一下用http去下载，不管本地还是服务器都有这个问题。也有测试user-anget 之类的，但还是一样下载timeout。

使用qq客户端下载群文件正常，使用mirai获取到的链接进行下载经常timeout

timeout设置 10分钟
群文件大小 1mb

这个可能是qq服务器有什么限制，有什么办法可以解决吗？
