<div dir="ltr">Hi all,<div><br></div><div>After hunting ghosts this weekend, I finally found the problem.</div><div><br></div><div style>- Both my host and controller had firewalls set up blocking AMQP messages</div><div style>
- RabbitMQ binds to **all** network interfaces through :::5672. Previously I believed this to be only v6 addresses. I realize now that if the flag IPV6_V6ONLY is not set, the IPv6 socket will serve both IPv4 and IPv6 traffic. It can be misleading when reading the output of netstat but that is not an OpenStack problem</div>
