With external IP, I mean the floating IP address which is assigned to the Kilo VM on OpenStack.

I use an OpenVPN VM on OpenStack to connect to the internal IP 10.0.0.16 of the kilo-vm:

[root@kilo-rc1 ~]# openstack-status

== Nova services ==

openstack-nova-api:     active

......

== Horizon service ==

openstack-dashboard:   500

...

neutron-lbaas-agent: inactive (disabled on boot)

(alle other services are active)

and in the log file I see:

[root@kilo-rc1 ~]# tail -f /var/log/httpd/horizon_error.log

Hi Arash,

I was getting a similar issue, and I changed the SECRET_KEY in /etc/openstack-dashboard/local_settings to some random letters, as in SECRET_KEY = '1245g789sdfgr697jg8asdn5' , and my dashboard started to work. For reference, my error was as below, not sure if it is anything similar to yours

Which external IP do you mean? Please explain your network setup.

Please try service httpd restart then check for clues in
/var/log/httpd/horizon_error.log.
openstack-dashboard-2015.1-dev2.el7 worked for me but in a small VM
with 2G RAM and 1G swap I've seen oom-killer in action and httpd was
the first victim, ps_mem shows httpd using >300MB after short browsing
openstack-dashboard pages...
