今天在调试一个自动 Let's Encrypt SSL 续期脚本的时候看到的一个错误:
An unexpected error occurred:
There were too many requests of a given type :: Error creating new authz :: Too many failed authorizations recently.
然后查到了这个:
https://community.letsencrypt.org/t/how-long-i-got-block-from-invalid-authorization/31584
如果每个域名、账号在一个小时内触发了 5 次失败的验证,那么就需要等待 1 小时再试。
