Why does nova-novncproxy blank screen and doesn't connect? - ignoring socket not ready

Every time I try to connect to an instance's VNC console (via Horizon or nova get-vnc-console server novnc) the proxy doesn't connect and sits with a nice black screen. The log /var/log/upstart/nova-novncproxy.log reveals nothing, and the consoleauth logs show requests for the connection, but from what I can tell it looks like novncproxy doesn't do "check_token".

I have followed the instructions from the docs. I can glean no more on the issue from elsewhere around the internet, help please! :)

Here's the services I'm running:

Controller: - nova-{api,scheduler,conductor,novncproxy,consoleauth,cert} - quantum-{server,plugin-openvswitch-agent,l3-agent,dhcp-agent} - glance-{api,registry} - cinder-{api,volume,scheduler}

Compute: - nova-compute - quantum-plugin-openvswitch-agent
