We've determined that an error made it possible for TLS-ALPN-01 challenges, completed before today, to not comply with certificate issuance requirements. We have remediated this problem and will revoke all unexpired certificates that used this validation method at 16:00 UTC on 28 January 2022. Please renew your certificates now to ensure an uninterrupted experience for your site visitors.

If you received the e-mail, then your account has successfully obtained at least one certificate in the last 90 days that was validated using the TLS-ALPN-01 challenge. All certificates issued in the last 90 days and validated with TLS-ALPN-01 challenge are affected. You need to force renew the certificate according to your ACME client’s directions. Threads may already exist in the forum regarding early renewal for a specific client and you can use the search function to see similar posts.

简而言之，一个错误导致今天之前使用 TLS-ALPN-01 签发的证书不满足发行需求，会在 1 月 18 日吊销。需要强制重新签发。

建议检查邮件或者检查证书看是否受影响，毕竟马上春节了。
