I added my internal IP to duckdns (192.168.x.x) - if I go into NGINX Proxy Manager and add the SSL Certificate, when I try to connect using a DNS Challenge I get this error:
Internal error
CommandError: usage:
certbot [SUBCOMMAND] [options] [-d DOMAIN] [-d DOMAIN] ...
Certbot can obtain and install HTTPS/TLS/SSL certificates. By default,
it will attempt to use a webserver both for obtaining and installing the
certificate.
certbot: error: unrecognized arguments: --dns-duckdns-credentials /etc/letsencrypt/credentials/credentials-35 --dns-duckdns-no-txt-restore

I went into my port forwarding and I added
Port: 80,443
Forward IP: IP address of my NGINX server
Forward Port: 80,443
But it still doesn't work. I'm not entirely sure what I am doing wrong.
