Cookie SSO and too many redirects error

After upgrading to 10.1.7414.  I'm trying to implement Cookie SSO.  I'm getting too many redirects error in IE and Chrome.  Nothing is logged in the exceptions table.  I'm assuming there is an issue reading the cookie, but without an error, it's hard to pin point the issue.  I have ensured the machine key is the same for both.  I can see the Request and Response Cookies and it's the same, but TC keep redirecting to my login page with creates the cookie and send it back to the ReturnUrl
