Hey Lawrence, The nc -z is checking that you can connect to the port, but the error itself looks to be related to the handshake when using SSL certificates in rabbitmq.
"getrandom() initialization failed. (_ssl.c:590)" being the important bit there. You'll probably find more if you start searching around that area rather than the connection failure itself. On a side note - this sounds like it may well be a bug with SSL certs in rabbitmq in OpenStack-Ansible, I'd love to get that fixed if that is the case! Hope that helps though.
