After Creating new site – new site is not found

Hi,

I just installed WP Multisite and follow the directions carefully but somethings gone wrong because after I create a new site it is not able to be found.

First I did get an warning after creating multi site:

Warning! Wildcard DNS may not be configured correctly!
+++++++++++++++++++++++++++++++++++++++++++++++++++++++
The installer attempted to contact a random hostname (33c958.milkywaydigitalmedia.com) on your domain. This resulted in an error message: Couldn’t resolve host ’33c958.milkywaydigitalmedia.com’

To use a subdomain configuration, you must have a wildcard entry in your DNS. This usually means adding a * hostname record pointing at your web server in your DNS configuration tool.

You can still use your site but any subdomain you create may not be accessible. If you know your DNS is correct, ignore this message.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
I checked my subdomain configuration, it is set up as below:

public_html/milkywaydigitalmedia.com – I used the “*” wildcard DNS

Here is my .htaccess file:

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
# END WordPress

And my wp-config.php

/**
 * For developers: WordPress debugging mode.
 *
 * Change this to true to enable the display of notices during development.
 * It is strongly recommended that plugin and theme developers use WP_DEBUG
 * in their development environments.
 */
define('WP_DEBUG', false);
define('WP_ALLOW_MULTISITE', true);
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'milkywaydigitalmedia.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

My Site link is https://milkywaydigitalmedia.com/

The thing that bothers me and I don’t understand is in the warning that says “Couldn’t resolve host ’33c958.milkywaydigitalmedia.com'” . I don’t know what the “33c958” is referring to:

Any help or suggestions would be greatly appreciated!!
Thanks
