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. crt.sh | 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: http://www.decimusadvisory.com
I ran this command:
sudo certbot --nginx -v
It produced this output:
Waiting for verification...
Challenge failed for domain www.decimusadvisory.com
http-01 challenge for www.decimusadvisory.com
Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Domain: www.decimusadvisory.com
Type: dns
Detail: DNS problem: looking up CAA for www.decimusadvisory.com: DNSSEC: Bogus: validation failure <www.decimusadvisory.com. CAA IN>: nodata proof failed from 162.159.25.175
Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.
