Here are a few suggestions on how to troubleshoot VNC issues.

Check if VNC is running:

 [root@icehouse1 ~(keystone_admin)]# systemctl | grep VNC
    openstack-nova-consoleauth.service                                                               loaded active running   OpenStack Nova VNC console auth Server
    openstack-nova-novncproxy.service                                                                loaded active running   OpenStack Nova NoVNC Proxy Server

Check if there are firewall rules preventing connections:

    [[root@icehouse1 ~(keystone_admin)]# iptables-save | grep vnc
    -A INPUT -p tcp -m multiport --dports 6080 -m comment --comment "001 novncproxy incoming" -j ACCEPT

Is the VNC port open and the daemon listening?

[root@icehouse1 ~(keystone_admin)]# netstat -anpt | grep 6080
tcp        0      0 0.0.0.0:6080            0.0.0.0:*               LISTEN      2376/python
tcp        0      0 192.168.1.127:48457     192.168.1.127:6080      ESTABLISHED 8856/chrome
tcp        0      0 192.168.1.127:6080      192.168.1.127:48457     ESTABLISHED 9267/python
[root@icehouse1 ~(keystone_admin)]# ps -ef | grep 9267
nova      9267  2376  0 08:06 ?        00:01:08 /usr/bin/python /usr/bin/nova-novncproxy --web /usr/share/novnc/
