I do not get any error while trying to access feed content for google sites from application hosted on gmail authenticated account. But I get
Token invalid - Invalid AuthSub token.
when I try to access application from google apps accounts managed GAE application.
I have tried both https://sites.google.com/feeds/ and http://sites.google.com/feeds/
I have also noticed that when Authsub prompts for grants access the address is taken as domain name address of site something like extra.mydomain.com whereas when page is loaded it is redirected to Google sites address https://sites.google.com/a/mydomain.com/pagename
The windows client is able to access the feed of same site whereas the web app is not getting through.
