Debugging Horizon Login Issues

Sometimes when the VM boots, after a successful login, from the log file:

2015-06-10 17:36:04,821 1911 WARNING horizon.exceptions Recoverable error: Connection to neutron failed: HTTPConnectionPool(host='192.168.56.10', port=9696): Max retries exceeded with url: //v2.0/extensions.json (Caused by <class 'socket.error'>: [Errno 111] Connection refused)

2015-06-10 17:36:06,300 1911 ERROR django.request Internal Server Error: /dashboard/admin/

Traceback (most recent call last):

<several error logs>

ConnectionFailed: Connection to neutron failed: HTTPConnectionPool(host='192.168.56.10', port=9696): Max retries exceeded with url: //v2.0/extensions.json (Caused by <class 'socket.error'>: [Errno 111] Connection refused)

 If you are able to login via the Terminal,  you can access all the logs in /var/log

For this problem, start with /var/log/horizon/horizon.log

After successfully logging in via the Horizon UI, you see the following log entry in horizon.log:

2015-06-21 15:12:43,259 2432 INFO openstack_auth.forms Login successful for user "admin"

You will likely see some error messages in your version of horizon.log, and hopefully those give some clue as to what is going wrong.

You can similarly find the logs for all openstack components in /var/log/<component-name>
