I’ve successfully created and installed certificates by running
sudo ./letsencrypt-auto --apache -d 020apps.nl -d static.020apps.nl -d olie.020apps.nl
I then ran this command:
sudo ./letsencrypt-auto renew --dry-run
It produced this output:
The following errors were reported by the server:
My operating system is (include version): Debian 8.7
My web server is (include version): Apache 2.4
I can login to a root shell on my machine: yes
I’m using a control panel to manage my site: no
Should I worry? I don’t understand why setting up the certificates went fine but renewing the ones for the subdomains seems to fail.
FWIW, the domain’s DNS record doesn’t have a CAA entry.
