Thanks It worked after #SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

I had the same problem....

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': 'controller1:11211', } } If I use the fqdn (e.g controller1) in the location it fails, try changing it to the IP (e.g. 10.0.0.11 or 127.0.0.1).

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '10.0.0.11:11211', } }

I too faced the same problem ,

Comment out the line SESSION_ENGINE from /etc/openstack-dashboard/local_settings file.

This fixed my issue

Yes, this worked.

I figured out my problem: The problem is I did not see the note after you edit /etc/sysconfig/memcached file. I had to change this line -l 127.0.0.1 to this line -l MangementcontrollerIP (for Example-10.0.0.11). The IP that you set in mentioned file
/etc/openstack-dashboard/local_settings CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '10.0.0.11:11211', } } After the just run this command : systemctl restart memcached.service

Hope it will work for you ... if not Kindly paste you error.log file will trying to help you out ...

Yes, it did work. I had same problem and changing memcached location did work for me. However, I am sseeing "unexpected error" when browsing Network=>topology sections within horizon dashboard. Perhaps I need to configure network topology in the neurton.conf. Any suggestion.
