Current Behavior

问题描述

“cp.cloudflare.com” 不再可用，经常会导致节点报错，导致无法连接，可导致的错误包括

• no alive dialer,
• level=debug msg="Connectivity Check Failed" err=timeout,
• level=debug msg="Connectivity Check Failed" err="Head "http://cp.cloudflare.com": EOF".

实际表现为域名无法解析，同时报 Timeout 错误。

相关问题

NekoBoxForAndroid#722，该 Issue 提供了替代性方案。

Expected Behavior

正常解析域名，节点正确通过连接测试

Steps to Reproduce

我的 config。

Environment

• Dae version (use dae --version): 0.9.0
• OS (e.g cat /etc/os-release): nixos-24.11
• Kernel (e.g. uname -a): 6.6.76

Anything else?

修正 boostrap dns 同样与该问题相关 (指解析默认config中的DNS域名), ref；
