DNS problem NXDOMAIN

[sudobyter]

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:
www.crazztor.com
I ran this command:
certbot --nginx
It produced this output:

Hi @sudobyter, and welcome to the LE community forum

Did you spell that name correctly ("crazztor.com")?
[Is it "crazytor.com"?]
