服务端运行在Debian11，客户端运行在openwrt_x86

服务端无报错，客户端出现上述报错。

想请教一下是什么原因导致的。

[BlackTouma]

关闭passwall，用小火箭连接至openwrt上开放的shadowtls服务，运行一切正常，可以kx上网。passwall连接则会出现以上报错。

shadowtls为二进制文件，后台运行在openwrt上。

这个问题是连接造成的回环（不知道这个词是否准确）导致的，消耗掉了所有的端口资源，在passwall中的模式-路由器本机 TCP 代理模式/路由器本机 UDP 代理模式 选择为GFW，避免127.0.0.1的回环，TCP 默认代理模式/UDP 默认代理模式可以自由选择
