Mac not allowing access to site on port 80

Have installed on Mac Yosemite and all looks ok except that I can’t access sites in the browser. I can SSH into Local and can see the site running as expected via curl. And from the Mac host I can ping the site and get a response and can also access the database via Sequel Pro, and Mailhog in the browser too on port 4003. Just can’t access the site from the browser (“Unable to connect”). I’m getting “port 80: Connection refused” when trying to access via curl on the Mac host. Getting this whether the Mac’s firewall is turn off or on. Any ideas how to fix this?
