I followed the tutorial <<The Perfect Server - Debian 10 (Nginx, BIND, Dovecot, ISPConfig 3.2)>> During the installation it says this: ISPConfig is using acme.sh now as Let's Encrypt client. Install acme.sh using the following command: curl https://get.acme.sh | sh -s After installation I cannot associate certificates with my domains; i.e. I create the certificate but cannot activate it on the domain. Here are two screens that offer a multitude of choices and I can't do it. Note that this happens with the debian 10 Buster version whereas with debian 9 Ispconfig 3 everything is fine. How to set up certificate management with debian 10 Ispconfig 3 and acme.sh?
Please see here for the setps to find out why LE refuses to issue a cert to you. Follow the checklist from top to bottom and check each step. https://forum.howtoforge.com/threads/lets-encrypt-error-faq.74179/
