V2ray-core: windows平台下经常性的断联

[ileeoyo]

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）
4.21.3

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。
chrome上google，github等。vmess普通tcp方式

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）
windows平台下经常的断联，大约等待几秒，十几秒，几十毫秒不等，网络恢复正常。打开或者关闭mux都这样。安卓和mac平台正常

4) 你期待看到的正确表现是怎样的？
网络正常

5) 请附上你的配置（提交 Issue 前请隐藏服务器端IP地址）。

服务器端配置:

    // 在这里附上服务器端配置文件

客户端配置:

    // 在这里附上客户端配置

6) 请附上出错时软件输出的错误日志。在 Linux 中，日志通常在 /var/log/v2ray/error.log 文件中。

以前一直十分稳定，且没有做过任何配置改动，最近2天遇到同样的问题。主机ip有时可以ping的通，有时不行；SSH也一样经常断。如果传输大流量（如视频），似乎断的更快。我在想是不是墙升级了。。。现在正申请个CDN试试。

我的可以ping通，ssh上

这几天同样出现类似问题，不稳定，且流量一大就断，过一会又可以Ping通。我把传输协议换成kcp后，好像就正常了

感谢。我仔细琢磨了一下技术文档，也改了一下配置，确实可以上了，效果真是立竿见影（目前尝试了半个钟头尚未断开，之前不到5分钟就断），而且速度还提高不少，看720p视频无压力。唉，早知道能提速这么多，我也不等到今天才改了，白白浪费了之前每个月几百GB的主机流量。人呐，就是死到临头才有动力做出改变。。。

不过实在感觉有点奇怪，该不会是mkcp的伪装功能起作用了吧？也不知道这种能撑多久。。。看来还是要储备点CDN的技术才行，这墙我估计是真的升级了。

参照这个教程配置即可：
https://guide.v2fly.org/advanced/mkcp.html#%E5%AE%A2%E6%88%B7%E7%AB%AF%E9%85%8D%E7%BD%AE

（streamSettings里的type改成utp；downlinkCapacity固定填100；uplinkCapacity按需填写，填的越大网速越快，但消耗宽带越猛，一般填网速*2~3，注意这里单位是MB而不是Mb；其他的配置就保持你之前的就可以了）

感谢分享！！！谢谢

应该是运营商QOS的结果，尝试进行伪装，用kcp确实是个不错的办法

[ileeoyo]

那应该是你被运营商tcp阻断了，运营商qos，换了kcp用的是udp协议，你们当地暂时udp没有被阻断
