Letsencrypt - noip.com - Let's Encrypt .. .. request failed : Web-based validation failed : Failed to request certificate :

I’ve read a bunch of posts with others having the same issue, I just don’t know what to do.
I am using noip.com and have pointed to their name servers. I have not configured Bind DNS Server
in Virtualmin or on the server. Any ideas on what I’m missing.

This is the output when requesting a cert:

Your server isn’t answering on that URL ( http://www.iqutopia.com/.well-known/acme-challenge/MPXzLaSPofv3Y9cmn75rMykmleKM14JxLlrwZk_gMI0 ). Simple. Fix that problem, and your certs will validate.

I’ve been struggling with this all day. Would it be possible point me to an article that would show me how to set up www.domain.com and possible firewall configuration for ports within Virtualmin, or anything else that might help. I would really appreciate it. Thank you for your help.
