Subdomain not working in MU

I have created a subdomain. vn.isafyi.com and pointed it to my server. I can test subdomain and it shows apache test page so I know its working. I have a MU site for isafyi.com and I when in and created a new site. For some reason its not working. I have the correct info in wp-config and htaccess and have multiple other subdomains (ie co.isafyi.com, mx.isafyi.com) that do work. In the admin, it shows but when I click on it I get a page stating that the wp-admin folder is not found. I see that the folder was not created in the blogs.dir folder and I do not see any new additions in the db. The permission on blogs.dir folder is 755. I am using rackspace cloud server and I have had problems using ftp so I had to install an ssh uploader plugin to make it work. Could this be a permission issue?

Here is my wp-config

define('WP_ALLOW_MULTISITE', true);
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
$base = '/';
define('DOMAIN_CURRENT_SITE', 'isafyi.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

htaccess
