Hello everyone. I have ISPConfig 3 installed on a Debian 9 server. While creating a new website I was unable to register a new SSL certificate. Looking at LetsEncrypt logs It looks like this is because I still have an old certbot version installed (0.10.2) using the ACMEv1 API. Actual certificates are renewed but new ones can't be registered. I searched for all the possible options here and on others boards, but I am a little bit lost between certbot-auto, acme.sh etc and I don't want to try things I am not sure that will work or not, as I don't want my website to be down for too long. What should I do in that case without messing something ?
