Open Stack

Greetings,

I would recommend verifying you can ping addresses, and then inspect
firewall rules, since it sounds like the issue is rooted in the state of
the undercloud node. I'm unaware of any specific configuration which would
cause this, meaning you would realistically need to identify why the
packets are not making it through to the service.
