I’m using Caddy, which automatically uses Let’s Encrypt for certs. here’s the command I’m issuing and the output I’m getting. the problem seems to be with LE:
# /usr/local/bin/caddy -log stdout -agree=true -conf=/etc/caddy/Caddyfile -root=/var/tmp -email firstname.lastname@example.org

I’m not running anything on 443 but as is obvious from above the real problem seems to be of name resolution
what else can I try to make this work?
