I'm attempting to set up Let's Encrypt for my Nextcloud instance.
However, there's a complication: I'm using a CGN (Carrier-Grade NAT),
which means my public IP address is different from my WAN (Wide Area
Network) IP address. Because I have to forward traffic to my WAN IP,
Certbot is unable to verify that I own the subdomain because it
doesn't point to my public IP. Is there a solution to this issue?
