I deployed a RabbitMQ instance as a web service following this guide: Deploy RabbitMQ | Render · Cloud Hosting for Developers.
As far as I understand it, it should expose its 5672 port for TCP connections to other render services under the hostname ‘rabbitmq-12345’, if it’s running on ‘rabbitmq-12345.onrender.com’.
However, when trying to connect to rabbitmq-12345:5672 from a Spring Boot app (another web service on render using docker) it fails with a UnknownHostException : Name or service not known.
What am I doing wrong here?
Thanks for your help.
