Hi Amza,

My apologies for only getting back to you right now.

We've been seeing similar SSH connectivity issues in gate checks and have
what we believe is a solution in a review in flight [1]. The patch is
easily implemented in your environment.

Failing that I have a few suggestions:

1 - Implement using at least the tag 12.0.1 as we fixed some pretty crucial
release bugs between 12.0.0 and 12.0.1. You can also implement from the
head of the Liberty branch.
2 - If your host(s) are a little slow you may wish to implement an
increased delay in /etc/openstack_deploy/user_variables.yml using the
variable 'ssh_delay'.
3 - If possible, try and catch us in the Freenode IRC channel
#openstack-ansible - there're often people there who can help you
troubleshoot.
