Thanks for opening this issue!

@Karmylr juicity?

[Karmylr]

@Karmylr juicity?

trojan

[mzz2017]

@Karmylr 节点在测联通性失败时是会被禁用一段时间的

[Karmylr]

哦

[Karmylr]

@mzz2017 连通性检查似乎不准确，节点可以使用但是还是报warningfailed to select dialer from group proxy (tcp6): no alive dialer

[Karmylr]

而且家里的宽带没有IPv6，但是却显示了tcp6

[mzz2017]

正常

[Karmylr]

那节点在其他软件可以使用，dae还是报failed to select dialer from group proxy (tcp6): no alive dialer并无法使用怎么办

[mzz2017]

打开 allow_insecure 试试

[Karmylr]

节点确实需要跳过tls证书验证，但是打开daed上的允许不安全还是会报failed to select dialer from group proxy (tcp6): no alive dialer

[mzz2017]

@Karmylr 那能用吗

[Karmylr]

刚启动时可以科学 过一段时间除了电报 其他国外网站无法访问 我再观察观察吧

[mzz2017]

@Karmylr 那你可以检查一下是不是 check url 的问题

[Karmylr]

目前是这样的，要改吗

[Karmylr]

顺便问一下，为什么要设计成节点连通性失败就禁用一段时间呢，为了自动故障转移吗

[mzz2017]

@Karmylr 只有电报能用说明是 dns 出问题了，你可以把 dns 那边的 googledns 改成 tcp:// 开头

[piyoki]

@mzz2017 好提議

[Karmylr]

@mzz2017 全部使用国内的dns服务器，能正常解析出google等国外网站的ip，但是还是会在开启dae一段时间后无法科学

[mzz2017]

奇怪，那为什么tg是可以的

[Karmylr]

tg再过一段时间也断网了

[mzz2017]

@Karmylr 开 debug 日志，看一下 connectivity check

[Karmylr]

@mzz2017 time="Sep 01 11:19:39" level=debug msg="Connectivity Check Failed" err="[Tls]: dial to south.steamdownload.top:11002: dial tcp: lookup south.steamdownload.top on [::1]:53: read udp [::1]:40327->[::1]:53: i/o timeout" network="tcp4(DNS)" node="2.香港 02"

[mzz2017]

@Karmylr 你是不是在用 dnsmasq，把dnsmasq里的劫持关了

[Karmylr]

@mzz2017 在用ImmortalWrt，怎么关劫持呢

[piyoki]

@Karmylr 那默認會有dnsmasq

[mzz2017]

@Karmylr 我不知道怎么关劫持，要么把 dnsmasq 监听端口设0，要么把dnsmasq的劫持关掉

[piyoki]

@Karmylr 參考 #79

[Karmylr]

这么干ImmortalWrt就没有DHCP服务器了吧

[mzz2017]

@Karmylr #171 (comment)

[Karmylr]

加pname(dnsmasq) -> must_direct解决了

[Karmylr]

用这条路由稳定了两个小时，刚刚又出现了

似乎connectivity check通过了，但是还是偶尔没法科学

[mzz2017]

上游不要写 dnsmasq

[Karmylr]

上游不要写 dnsmasq

dae的upstream没有dnsmasq
加入pname(dnsmasq) -> must_direct这条路由之后的断流会自己在几秒后恢复，而且频率不高

[Karmylr]

取消勾选dnsmasq的dns重定向解决了
