Following through the tutorial (https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-18-04), when trying to obtain an SSL cert in Step-4 (sudo certbot --nginx -d <mydomain>.com -d www.<mydomain>.com), I get the following error:
-
The following errors were reported by the server:
Domain: www.<mydomain>.com Type: None Detail: DNS problem: NXDOMAIN looking up A for www.<mydomain>.com
- check that a DNS record exists for this domain
Domain: <mydomain>.com Type: None Detail: DNS problem: NXDOMAIN looking up A for <mydomain>.com - check that a DNS record exists for this domain
I have done this many times in the past for other domains and this is the first time I get an error. I have made all the prerequisites mentioned at the beginning of the article, as always, but still I cannot figure where the problem is.
