Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: https://academia.techcomputerworld.com
I ran this command:
certbot --nginx -d academia.techcomputerworld.com -d www.academia.techcomputerworld.com
It produced this output:
certbot --nginx -d academia.techcomputerworld.com www.academia.techcomputerworld.com
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.
