DNS problem: NXDOMAIN looking up A

My domain is: shinyserv.es

I ran this command: sudo letsencrypt certonly -a webroot --webroot-path=/var/www/html/ --domain shinysrv.es

It produced this output:

This domain doesn't appear to be registered.

Did you mean to type shinyserv.es in your Certbot command?


Ah, that's gotta be a classic, the good old typo on the command line :laughing:


Yes, my bad, wrong typing... Thank you! Now I get different errors that I need to check out :slight_smile:


Good luck! I hope you manage to fix the next hurdle. If you don't manage to figure it out yourself, you're always welcome here.
