我正在尝试自动更新我的 Let's encrypt 证书。为此，我使用了 certbot，它将在我的 DNS 条目中写入 TXT 记录。不幸的是，此更新一直处于 PENDING 状态。如果我在 certbot 等待时手动更新 TXT 记录，一切正常。这些更新保持在 PENDING 状态的原因可能是什么？

我不知道软件背后的细节，它只是一个带有适当参数的 certbot 命令来更新证书。为此，该软件会在 DNS 中创建一个 txt 记录，然后验证该 txt 记录是否存在。这证明我是拥有正确权限的所有者。之后，将发布新证书。由于 txt 记录的创建/更新仍处于挂起状态，因此 certbot 无法验证并将失败。如果我通过 Google DNS 手动更新记录，而 certbot 正在小睡进行传播，一切正常。唯一的问题是这些操作未执行，但仍处于待处理状态。

使用的命令是：

certbot certonly --dns-google --dns-google-propagation-seconds 120 --dns-google-credentials ~/bin/dns-hosting-331818-0437a910973f.json -d "*.famderidder.com"
