Can not authenticate to jabber.org

Authentication via the gateway to jabber.org does not work. Authentication directly to jabber.org via Spark is fine. There error I get when authenticating via the gateway is:

2008.02.12 09:50:35 xmpp user's login/password does not appear to be correct: mtstravel
