Open Stack

Hi list,

I'm working under CentOS with icehouse.

I'm trying to enable VNC console for instances.

While my api node has 2 physical NICs, one with IP 172.16.24.2, another one with IP 192.168.40.121.
The compute node has only one NIC with IP 192.168.40.127.

I configured nova.conf on api node with:
novncproxy_base_url=http://172.16.24.2:6080/vnc_auto.html
vncserver_proxyclient_address=192.168.40.121
vnc_enabled=true

nova.conf on compute node with:
novncproxy_base_url=http://172.16.24.2:6080/vnc_auto.html
vncserver_listen=0.0.0.0
vncserver_proxyclient_address=192.168.40.127
vnc_enabled=true

Also I start services openstack-nova-novncproxy & openstack-nova-cert & openstack-nova-consoleauth on api node too.
Then I try to run command "nova -debug get-vnc-console my_instances novnc"
I get error:
