Domain Publishing Issue - Causing SEO Problem On Google My Business

I am having two main issues here.

  1. Firstly, when I try to unpublish the WWW. version of my domain, I get a 404 page upon loading the site.

  1. I am trying to get rid of the WWW because Google My Business is not permitting my website and I think it has to do with the fact that I have two versions of the url published.
