kcp模式下，Github上传图片失败

comwrg commented 5 years ago

提交 Issue 之前请先阅读 Issue 指引，然后回答下面的问题，谢谢。除非特殊情况，请完整填写所有问题。不按模板发的 issue 将直接被关闭。如果你遇到的问题不是 V2Ray 的 bug，比如你不清楚要如何配置，请使用Discussion进行讨论。

1) 你正在使用哪个版本的 V2Ray？（如果服务器和客户端使用了不同版本，请注明）服务器： 3.50 客户端：3.47 2) 你的使用场景是什么？比如使用 Chrome 通过 Socks/VMess 代理观看 YouTube 视频。 KCP模式下，使用Chrome将图片拉进Issue内容框上传图片 3) 你看到的不正常的现象是什么？（请描述具体现象，比如访问超时，TLS 证书错误等）

上传速度会直接到满速几秒钟（大概2M/s，图片大概2M）之后就无法通过代理上网（但是ssh可以连接），过几分钟后自动恢复

4) 你期待看到的正确表现是怎样的？上传成功 5) 请附上你的配置（提交 Issue 前请隐藏服务器端IP地址）。

8) 其它相关的配置文件（如 Nginx）和相关日志。

9) 如果 V2Ray 无法启动，请附上 --test 输出。

通常的命令为 /usr/bin/v2ray/v2ray --test --config /etc/v2ray/config.json。请按实际情况修改。

10) 如果 V2Ray 服务运行不正常，请附上 journal 日志。

通常的命令为 journalctl -u v2ray。

请预览一下你填的内容再提交。

尝试将搭建服务器在本地连接上传，结果是可以上传

猜测是GFW检测到某些异常后将包直接丢弃（理由：查看服务器的下载流量并为大幅度增长）（异常似乎跟图片大小有关系，几百KB的可以上传成功，但是几MB的上传异常，不过kcp是基于udp分片传输的，按道理应该没啥关系。。）

并封禁该端口几分钟（理由：尝试代理无响应状态下使用不同IP连接，并未响应（几分钟后恢复），但ssh仍可以连接）

你这种情况，我经历过，原因就是运营商对UDP的QOS，当UDP流量过大，会封锁该远程IP的UDP连接，但TCP不受影响。

了解了,谢谢~
