So it looks like ISConfig is not working correct for me. What happens is the same as in this video that I found: I can activate it when I create a new site but it will not keep the activation. The certificate will be generated but it will just not be activated afterwards. If I do it again cerbot just shows me this: What have I done?: I have updatet certbot-auto like this: Also tried Debian apt-get install certbot-auto but it's the same problem. I also downloaded the newest version of ISPConfig (3.1.13p1), ran the update.php again and said yes to every question except create a new certificate. Still no luck. Is there a fix for this or am I doing something wrong?
