curl和服务里可达情况不同的排查
curl 刚才连上了拿 200但 Node失败Node fetch每次都失败 —— IPv4 报 ETIMEDOUT 10.110.71.225IPv6 报 EHOSTUNREACH 2001::3b18:3adNode/undici Happy-EyeballsautoSelectFamily IPv6 干扰。/etc/hosts只给了 IPv4但 DNS 又返回了一个不可达的 IPv62001::3b18:3adNode 双栈并发去连IPv6 把整个连接搅黄了。解决方案关掉 autoSelectFamily 启动网关的命令配置路径在/Users/sh02037ml/.zshrcecho export NODE_OPTIONS--no-network-family-autoselection --dns-result-orderipv4first ~/.zshrc
