[Users] oVirt 3.3 SPICE console error 500

Hello, I upgraded oVirt to 3.3 and when I want to launch SPICE console I get error 500 on web ui. I tried to install websovketproxy package, enabled it by "engine-config -s WebSocketProxy="Engine:6100" " But it did not help. I dont know what I did wrong. Logs are bellow. Thank you for advice ==> ovirt-engine/engine.log <== 2013-07-25 15:22:31,717 INFO [org.ovirt.engine.core.bll.SetVmTicketCommand] (ajp--127.0.0.1-8702-8) Running command: SetVmTicketCommand internal: false.
