>SOLUTION

Check the following:

1.Usually, the console management uses 15672 port.

2. Usually, the HTTP request via app (web service/microserve) uses 5672

3. Make sure to enable these ports when working with container (docker).

4. Avoid using /api  on a RESTful web service because "/api" is already used by the native rabbitmq's ws,

An example of the properties file (application.yml):

  rabbit-host: mydomain.com 

  rabbit-port: 5672

  rabbit-ssl: false

  rabbit-user: john doe

  rabbit-pass: secret
