[yelosheng]

你可以尝试把客户端的8388端口换一个其它的试试，有可能你系统里某个别的程序也在使用这个端口，导致冲突。

[KevinLoveGitHub]

@yelosheng 应该不是这个问题，这个端口一直没有被占用

[snaigle]

我的kcptun 通道也不行了，现在用直连

[zuoshouzz]

我的一直这样....

[xiebruce]

@KevinLoveGitHub @snaigle 是看油管了？或者看其他视频了？或者下载了？有可能是流量大被ISP封了（就是被你所在的地方那个网络封了，比如你家用的是电信，那可能是电信把它封了，因为kcp用的是udp，流量大会被封，最简单的测试方法是手机开个热点给电脑，看能不能用kcptun，能的话，就是被ISP封了）[Kcp用着用着偶尔就会断开{伪解决方案} ] (https://github.com/xtaci/kcptun/issues/228)

换成了最新版本的，目前没有问题

[xiebruce]

@KevinLoveGitHub 可能你少看视频吧，我看油管看的多，还开1080，直接被isp封了，另外，很多人遇到这个问题：https://github.com/xtaci/kcptun/issues/228(https://github.com/xtaci/kcptun/issues/228)

确实看油管了，现在用直连+bbr，速度也不错

[xiebruce]

我现在还是直接用kcp看油管，没啥事，之前被封了一整天后来解封了，是因为我开了4k视频（2160p），现在我看1080p没啥事，只要不连续看个不停，我那次被封好像是半天都在看油管

你用的哪家的 vps，我现在用的看4K有点费劲

[xiebruce]

不建议看4k啊，看4k很容易封，看1080p就可以，我用的hostus，另外跟你的机房位置有关，如果机房位置远，你选哪家都没用
