Unable to connect to Horizon on Microstack

Microstack works well on my side. Only, when I want to use the Horizon interface on, I enter my login and password and I land on this.

“Unable to create a new session key. It is likely that the cache is unavailable.”

How can I solve this problem? I’ve been stuck on it for several hours.

Thank you in advance for your valuable help and support :slight_smile:

I fixed mine by following this.

In /etc/memcached.conf,

# Specify which IP address to listen on. The default is to listen on all IP addresses # This parameter is one of the only security measures that memcached has, so make sure # it's listening on a firewalled interface.
