Problems configuring HTTP binding

I am trying to get the Candy.js (http://amiadogroup.github.com/candy/) example working with ejabberd over BOSH using HTTP binding. Here is where I'm at: I can connect to my ejabberd server with a regular XMPP connection through Pidgin. I know I have my proxy (nginx) set up correctly because I can browse to the URL I specified in the nginx config file and it will return with the standard ejabberd mod_http_bind page. My only problem is I cannot complete a connection to my ejabberd server over BOSH through HTTP binding. Here is the debug information the Candy.js example spits out into the JavaScript developer console in Google Chrome (with the XML stanza data removed):
