Horizon log in fails by "Something went wrong!" error
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.
