In another thread many folk have mentioned that their Google Reader recipe has stopped working. The error they experience is HTTPError: HTTP Error 401: Unauthorized.

Spoiler:

Below is a snippet of conversation from the other thread. I think I may have pointed to the reason for the error but unfortunately I lack the knowledge/experience needed to help these folks.

This post entitled "Changes to sending authenticated requests to Google Reader" on the Google Reader Blog might hold the key but I don't have the skill set needed to correct the problem.

Looking at the code in the first post of this thread convinces me that your link does hold the key. The current recipe finds and uses the SID cookie. Google stopped using SID cookie authentication and now wants an AUTH header. I'd ask for help in the dedicated recipe thread and make sure you include the link above. I don't use GoogleReader and I've only played around with adding headers and mechanize once.

I Hope someone here might be able to work out this piece of the puzzle and get this recipe working again.
