Hi, I install openstack in 3 nodes, I log in properly in horizon dashboard until last 2 days. After that when I start my nodes and want to log in in to openstack web UI, after inter username and password, this error appeared in one page:

Something went wrong! An unexpected error has occurred. Try refreshing the page. If that doesn't help, contact your local administrator.

In my log file in controller node /var/log/apache2/error.log this error was shown:

[Sat Jun 13 03:53:14.849140 2015] [:error] [pid 2529:tid 139688881870592] ConnectionFailed: Connection to neutron failed: HTTPConnectionPool(host='controller', port=9696): Max retries exceeded with url: /v2.0/extensions.json (Caused by <class 'socket.error'="">: [Errno 111] Connection refused)

Thanks for your suggestion.

did you restarted neutron-server services on network and controller node. Did you try restarting httpd and memcached service?

the physical ethernet connection to controller from neutron may be disconnected or your neutron-server service may be down.

first check wheather you are able to ping between neutron & controller.

then check wheather messaging service is running or not.

I would suggest you look into your services to determine wether or not they are all running as intended. On a controller node you can try the following:

nova service-list
neutron agent-list
rabbitmqctl status

Alternatively, you can also run the following commands to get a response from the OS:

On Ubuntu:

cd /etc/init.d; for i in $(ls nova-*); do service $i status; done
cd /etc/init.d; for i in $(ls neutron-*); do service $i status; done

On CentOS:

cd /etc/init.d; for i in $(ls openstack-nova-*); do service $i status; done
cd /etc/init.d; for i in $(ls openstack-neutron-*); do service $i status; done

If you can post the responses from these commands perhaps we can determine what the problem is.
