最新版从 Let's Encrypt 获取证书失败

星魂

设备环境：物理机、公网、系统v1.1.15

BUG现象：在DDNS为DNSPod.cn服务商情况下，使用从 Let's Encrypt 获取证书失败，查看DNS的TXT记录有正常的添加和删除记录

DNS propagation timeout, error: error: one or more domains had a problem:
[xx.xxxx.com] propagation: time limit exceeded: last error: [zone=xxxx.com.] could not determine authoritative nameservers

以上是错误代码

出现频率：必现
