Hi all!
On Monday, I re-set up my web server (previously on a Raspberry Pi) in the cloud and wanted to recreate the certificate via Certbot. It worked until yesterday, however, when you go to the page, you get a message that the certificate has expired since 01/03. However, the output from certbot says something different (Expiry Date 01.06.2021).
Hope you can help me! 
My domain is: [heilpraxis-hofmann-protoschill.spdns.de]
My web server is (include version): i use nginx and php and mysql
The operating system my web server runs on is (include version): Centos 8
My hosting provider, if applicable, is: [netcup.de]
I can login to a root shell on my machine (yes or no, or I don't know): yes
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): --1.12.0
