[SOLVED] Unable to join race on local server

I installed the code rally server following th guide on IBM.

It runs, I can access the server information page and see the leaderboard. But when I try to enter with Eclipse I get a

"Unable to enter Keepertje on Localhost"

I also try to connect with the nodeclient found on Github, but there I also cannot authenticate. Am I missing something?

Kind regards,. Cindy

My Server.xml:

<!-- Enable features -->
<featureManager>
    <feature>webProfile-7.0</feature>
    <feature>localConnector-1.0</feature>
    <feature>websocket-1.1</feature>
</featureManager>

<!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
<httpEndpoint httpPort="9080" httpsPort="9443" id="defaultHttpEndpoint"/>

<!-- Automatically expand WAR files and EAR files -->
<applicationManager autoExpand="true"/>


<applicationMonitor updateTrigger="mbean"/>

<webApplication id="CodeRallyWeb" location="CodeRallyWeb.war" name="CodeRallyWeb"/>
