Getting Ghost to recognize use of www sub-domain and no sub-domain

I’ve setup a new Ghost blog on Ubuntu 16.04 at pricelesspricing.com. That works fine. However, when I go to www.pricelesspricing.com I get a screen telling me to setup Ghost.

I currently have a CNAME record directing www.pricelesspricing.com to pricelesspricing.com I have an A record for pricelesspricing.com that directs it to by site IP

What I’ve tried:

1. Add both domains to SSL using certbot
2. Added both domains to Ghost config under server_name
3. Restarted Ghost and NGINX
4. NGINX and Ghost config now show: server_name pricelesspricing.com www.pricelesspricing.com

I’m stuck now and not sure what else to try. Can anyone help please?

Thanks.
