This morning, a custom recipe I've been using for a few months failed with "An existing connection was forcibly closed by the remote host". The recipe simulates a login to the site's daily newspaper and then scrapes the HTML, so I tried manually logging in, and everything works fine.

Does anyone have any ideas what I can do to debug this? Is there a way to get more details about the error or to tell why the force-close happened?

I've attached the recipe (it requires a username and password to the Boston Globe). Here's the failure trace:
