Hi,
According to our records, your Let's Encrypt software client renewed a
TLS/SSL certificate recently using the ACMEv1 protocol. Here are the details
of one recent ACMEv1 request from each of your account(s):
Client IP address: 2a01:238:4387:cc00:1027:fc0d:cfe6:c387
User agent: CertbotACMEClient/0.17.0 (certbot; Debian GNU/Linux 8 (jessie))
Authenticator/webroot Installer/None (renew; flags: n) Py/2.7.9
Hostname(s): "verwaltung.zapfev.de"
Request time: 2021-01-10 11:17:32 UTC
On June 1, 2021, you will no longer be able to renew your certificates using
ACMEv1. You should upgrade to an ACMEv2 compatible client before June 1, or
certificate issuance will fail. Until then, we will also have occasional
ACMEv1 issuance and renewal brown-outs each month:
January
* Tuesday, 26th (6 hours)
February
* Wednesday, 10th - Thursday, 11th (24 hours)
* Thursday, 25th - Friday, 26th (24 hours)
March
* Monday, 15th - Tuesday, 16th (48 hours)
* Wednesday, 24th - Thursday, 25th (48 hours)
April
* Tuesday, 6th - Thursday, 8th (72 hours)
* Friday, 23rd - Sunday, 25th (72 hours)
May
* Thursday, 6th - Monday 10th (5 days)
* Tuesday, 18th - Tuesday, 25th (7 days)
The Staging ACMEv1 API will be fully disabled on March 26, 2021. Until that
date, it will undergo brownouts on the same schedule as the Production ones
above.
For most people, simply upgrading to the latest version of your existing
client will suffice to begin using ACMEv2. You can view the client list at:

If you're unsure how your certificate is managed, get in touch with the
person who installed the certificate for you. If you don't know who to
contact, please view the help section in our community forum at
https://community.letsencrypt.org/c/help and use the search bar to check if
there's an existing solution for your question. If there isn't, please create
a new topic and fill out the help template.
