[ovirt-users] Problem connecting to ovirt-optimizer machine

Hello, I'm playing around with the optimizer. For a full CentOS 6 oVIRT 3.5.3 cluster, I've installed a CentOS7 ovirt-optimizer machine as described in "Trying out oVirt's Probabilistic Optimizer". All works fine... the only thing is, I can't get a connection form the engine. "Status: Data refresh failed: 0" When I try from this host a: GET /ovirt-optimizer/result/ ..... The requested resource (Could not find resource for full path: http://ovirt.optimizer:8080/ovirt-optimizer/result/) is not available. ..... server.log shows ... 16:44:01,841 FEIN [org.jboss.resteasy.core.SynchronousDispatcher] (http--0.0.0.0-8080-1) PathInfo: /result/ 16:44:01,842 FEIN [org.jboss.resteasy.core.SynchronousDispatcher] (http--0.0.0.0-8080-1) Failed executing GET /result/: org.jboss.resteasy.spi.NotFoundException: Could not find resource for full path: http://ovirt-optimizer:8080/ovirt-optimizer/result/ at org.jboss.resteasy.core.registry.Segment.match(Segment.java:81) [resteasy-jaxrs-2.3.2.Final.jar:] at org.jboss.resteasy.core.registry.SimpleSegment.matchSimple(SimpleSegment.java:33) [resteasy-jaxrs-2.3.2.Final.jar:] at org.jboss.resteasy.core.registry.RootSegment.matchChildren(RootSegment.java:327) [resteasy-jaxrs-2.3.2.Final.jar:] ...... Any tips, how to solve this? Thank you Hans-Joachim
