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/
