For some reason two of my servers, one running Deb 10 with nginx (nginx is new to me) and Deb 10 with Apache2 doesn't get any certs in ISPconfig 3. Any idea why it is like this?
The thing is that these two servers are in different locations (IP and country) and are on different domains.
I don't see where this matters for this problem, there are users that made the same mistake on dozens of systems until they found out what they did wrong. Use the FAQ, follow it step by step, to find out what you did wrong with these setups and why LE refuses to issue certs.
