I am running Ubuntu 18.04 with nginx and I am getting the following error when I try to generate a ssl certificate for my server using certbot:
Failed authorization procedure. irfreeman.ubuviz.com (http-01): urn:ietf:params:acme:error:dns :: No valid IP addresses found for irfreeman.ubuviz.com, www.irfreeman.ubuviz.com (http-01): urn:ietf:params:acme:error:dns :: No valid IP addresses found for www.irfreeman.ubuviz.com
IMPORTANT NOTES:
The following errors were reported by the server:
Domain: irfreeman.ubuviz.com
Type: None
Detail: No valid IP addresses found for irfreeman.ubuviz.com
Domain: www.irfreeman.ubuviz.com
Type: None
Detail: No valid IP addresses found for www.irfreeman.ubuviz.com
I would like to know if the problem comes from maybe a bad configuration or any other error.
If I try to deduct from this, I might think that there are no subdomain named irfree.ubuviz.com but I am pretty sure there is one.
