Custom DNS - Login Failures

Hello -

When using our custom dns to visit the site, i've found the following failure scenarios:
Start Page: http://code.rizon.net/account/signin/

Attempt to login via any OpenID method:

• http://code.rizon.net/social/google/redirect/
• http://code.rizon.net/social/facebook/redirect/
• http://code.rizon.net/social/twitter/redirect/
• http://code.rizon.net/social/github/redirect/

Will results in 404 page.
