I do not see any DNS configuration for marcosgaming.com
that points to Netlify. In fact, I see no A or CNAME records as shown in Zoho Toolkit.
First, decide if you want to use Netlify DNS or external DNS
Once decided, follow either the Netlify DNS or external DNS documentation and ensure you’ve correctly added the custom domain to your site.
