Wordpress Multisite Subdomain 404

I have created a multisite wordpress with subdomains (hosting is Bluehost). Everytime I try to access the subdomains (test.example.com) I get a 404 error message. I copied the code to wp-config and .htaccess. I created a wildcard subdomain (*.example.com) and creates a folder in my public_html .

Do I have to make changes to DNS records and what are those?
