Hello!! All the environments of this client that has front-ends are presenting communication errors with the RabbitMQ that is allocated in the controller machine. On the platform I found no errors about this but in the windows logs we have the ones specified in the attached documents. We have already tried restarting the services and machines but the problem persists, including the configuration tools connection test is successful.

I would say that maybe it's better for you to contact the Support.

But from previous experience, it's possible that you need to open ports and check firewall definitions in other for the other servers communicate with the one that as the RabbitMQ.

Please also check this documentation:

Here and here.
