描述问题
证书申请失败，报错如下：

[2025-03-15 20:22:37]
进入申请证书节点
[2025-03-15 20:22:47]
get directory at 'https://acme-v02.api.letsencrypt.org/directory': Get "https://acme-v02.api.letsencrypt.org/directory": dial tcp: lookup acme-v02.api.letsencrypt.org on 127.0.0.11:53: read udp 127.0.0.1:58178->127.0.0.11:53: i/o timeout

宿主机上可以ping通：

ping acme-v02.api.letsencrypt.org
PING ca80a1adb12a4fbdac5ffcbc944e9a61.pacloudflare.com (172.65.32.248) 56(84) bytes of data.
64 bytes from 172.65.32.248 (172.65.32.248): icmp_seq=1 ttl=58 time=2.64 ms
64 bytes from 172.65.32.248 (172.65.32.248): icmp_seq=2 ttl=58 time=0.492 ms

container中ping不通：

/app # ping acme-v02.api.letsencrypt.org
ping: bad address 'acme-v02.api.letsencrypt.org'

设置「DNS 递归服务器」后，依然不通，同样的报错
