Hi,
I am copying response from extension SME from internal request , see if below helps, if not based on your response we will involve extension SMEs, keep us posted, as we see host:port is missing in error URL only URI found:
"Your endpoint is not returning any data for the extension to process. Please verify whether you're using the right URL. Also, provide us with the o/p of
curl -kv http://<host:port>/api/federation-links"

Hi Barry,
Have you enabled federation plugin in RabbitMQ? if not, please take a look at https://www.rabbitmq.com/federation.html. Please file a help ticket in Zendesk with debug logs for faster resolution of the issue.
Thanks,

Hi Barry,
The following error is because you don't have the federation plugin installed on RabbitMQ instance.

Please refer here for more details (http://www.rabbitmq.com/federation.html).
In case of further issues, we suggest you to raise a heldesk ticket at help@appdynamics.com with all the configuration and log files.
Thanks
