Late last night our AD cert expired and was subsequently renewed (used for authentication). Authentication to our openstack was broken and eventually fixed (ie Users logging into Horizon). During this process we broke something somewhere else. When creating a new instance in any tenant we get the following errors/messages:

HORIZON message: Error: Failed to launch instance "<servername>": Please try again later [Error: No valid host was found. Exceeded max scheuling attmepts 3 for instance <splat>].
