支持我们
完整性要求
  • 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。
  • 我保证提供了可以在本地重现该问题的服务器、客户端配置文件与流程，而不是一个脱敏的复杂客户端配置文件。
  • 我保证提供了可用于重现我报告的错误的最简配置，而不是依赖远程服务器、TUN、图形界面客户端或者其他闭源软件。
  • 我保证提供了完整的配置文件与日志，而不是出于对自身智力的自信而仅提供了部分认为有用的部分。

Research direction

Start with protocol/direct/outbound.go at fetchMyAddresses and Outbound.Start, then trace the startup path through adapter/lifecycle_legacy.go and box.go. Reproduce the configuration under Termux on Android and identify why the direct outbound dereferences a nil value. Done means sing-box starts without the panic while preserving direct outbound initialization.
