I have installed openstack on centos . The dashboard was working fine until recently it was throwing some error: The httpd log shows this:

ensure that all your services are up and running.

Did you check that neutron server is up and running ? you can try 'service neutron status'. If not running restart using 'service neutron restart'

connection to neutron failed is clear case of reachability. Either IP is changed or port is changed or something is not running or name resolution is an issue. I feel you need to explain your setup further to solve. if you would like to chat with online, do let me know. I can share my email id.

Go to the mysql and run flush hosts command.

run following commands: 1. # mysql -u root -p 2. mysql> use keystone; Database changed 3.FLUSH HOSTS;

and Done. These steps resolved my issue !! hope this works for you as well !!
