完整性要求

  • 我读完了 issue 模板中的所有注释，确保填写符合要求。
  • 我保证阅读了文档，了解所有我编写的配置文件项的含义，而不是大量堆砌看似有用的选项或默认值。
  • 我提供了完整的配置文件和日志，而不是出于自己的判断只给出截取的部分。
  • 我搜索了 issues, 没有发现已提出的类似问题。
  • 问题在 Release 最新的版本上可以成功复现

描述

版本为 release 里 25.9.11 windows amd64

所提供的服务端客户端配置在同一台机器上运行

重现方式

在启动服务端和客户端后立即发起请求会看到内网端崩溃，如果是双方均等待了 10-20 秒则正常，但是如果任一一端关闭重启立即请求也会复现崩溃

curl -x socks5h://127.0.0.1:1080 https://www.gstatic.com/generate_204 -I
