UDP不能通訊

[elric8]

udp显示错误，TCP可以，手机上shadowrocket可以连接（udp不知道） 日志

手机端使用igniter 0.98, 服务器log出现相同错误

[p4gefau1t]

服务端的报错是因为 UDP 隧道长时间不活跃，连接被客户端关闭。

我使用其他 UDP 客户端的测试均正常，从日志来看很可能是你的客户端没有正确处理返回的 UDP 包。

另外 @HiFiPhile 的客户端日志是 UI 的日志，不包含任何关于连接的有效信息。

[HiFiPhile]

总结下来是这样的，也可能是Ignite的问题:

Ignite的log没有更多的信息

[elric8]

找到原因了 @p4gefau1t 只要開啓 多路復用 就會造成UDP大量報錯 現在關閉后，正常通訊

[GVMESS]

MUX不是特色功能么，开启MUX UDP报错是否有影响

[dotNetDR]

我也遇到同样问题 软路由模式:nat 开启了websocket 使用mux.enabled=true时，程序的udp包转发失败，把mux.enabled设为false就正常了

版本：v0.8.2

[hak0]

遇到同样问题 客户端: igniter-go 0.9.5beta-SNAPSHOT, qv2ray 2.6.3:5840, shadowrocket 最新版，开启多路复用后服务端报错：

failed to parse udp packet addr | unable to read ATYP | EOF

服务端版本0.8.2

[gaorui84]

遇到同样问题 PC客户端：V2RayN v4.19，Mux未开启 Android客户端：V2RayNG v1.6.14，无Mux选项 服务器端：Trojan-go v0.8.2，用 tls-shunt-proxy v0.7.0 分流反代 trojan-go 流量出现此问题，netstat 查看连接发现 trojan-go 进程产生大量 udp6 连接，改为 trojan-go 直接监听 443 端口后此问题消失。

[chr09670]

遇到相同的问题。 客户端用openwrt，passwall的trojan-go，服务端是容器p4gefau1t/trojan-go，配置除了添加ws和mux，其它都是默认的，在服务端日志也发现了这个问题[ERROR] 2022/05/26 01:46:38 github.com/p4gefau1t/trojan-go/tunnel/simplesocks.(*Server).acceptLoop:server.go:41 simplesocks server faield to read header | EOF
