<p dir="ltr">Hi all,</p>
<p dir="ltr">I'm using Mirantis Fuel 9 and I've deployed three nodes including Controller, Compute and Cinder. I can't access horizon after successful deployment or ssh to any node. (I can ping or ssh from inside of any node to other nodes in external network.)</p>
<p dir="ltr">Another question is when I'm going to deploy OpenStack with three Controllers, one Compute and one Cinder, I receive the following error:</p>
<p dir="ltr">Could not prefetch keystone_service provider 'openstack': Execution of '/usr/bin/openstack service list --quiet --format csv --long' returned 1: An unexpected error prevented the server from fulfilling your request. (HTTP 500)</p>
<p dir="ltr">What is the problem? Can you please guide me?</p>
