YouTube Direct AuthSub malformed request

Question

I'm using the YouTube Direct for Google App Engine. I go into the Admin section to authenticate my account, but when I do that, instead of logging me in, it redirects me to a page saying:

"The page you have requested cannot be displayed. Another site was requesting access to your Google Account, but sent a malformed request. Please contact the site that you were trying to use when you received this message to inform them of the error."

I'm pretty sure I setup my configuration properly. I even setup secure authsub so that when a user logs into his Youtube account through the app it says that the connection is secure. However, whenever I want to authenticate myself in the admin section, it gives me that malformed request. To avoid ambiguity, this is where I am trying to authenticate: http://i.imgur.com/F5sbs.png

Here is the request, if that helps:

I guess it's trying to access some info from my Google account and forward it to my App engine instance to the URL http://igivemoretest.appspot.com/admin/PersistAuthSubToken&secure=0

Answer 1

My Google account was not properly linked with Youtube. I'm not sure why this happens, but it happens with all my Google apps accounts. It works if I just create a regular Google account and use it.
