- 处理器体系结构：x64
- 系统版本号：Window11
- 下载渠道：Github
- 程序版本：Steam++_v3.1.0_win_x64
- 是否包含独立运行时：无

Start with BD.WTTS.Services.ProxyService.GetValidDNSAsync and NetworkTestService.TestDNSOverHttpsAsync, then reproduce the listed acceleration and HuggingFace access steps while reviewing the TaskCanceledException logs. Done means the accelerated GitHub/HuggingFace access path works without the reported cancellation failures.
