I have installed two different VPS with their corresponding hostnames:
server300.sistemaxxxxx.net
server301.sistemasxxxx.net
I have created A records pointing to the corresponding VPS server.
I cannot install Let’s Encrypt SSL for the panel or for any added domain.
The installation is clean and fresh on Ubuntu 24.04.
During installation, I set the hostname from the installation process, so running v-change-sys-hostname no longer makes any changes.
The first thing I do is run v-add-letsencrypt-host, and the error message says:
Error: ssl certificate key pair is not valid
Error: domain server301.sistemasxxxx.net does not have an SSL certificate.
Again, the installation is clean and new.
What could be the issue?
