I installed Mautic 5.1.0 successfully without any issues. I need a queuing system and wish to integrate it with RabbitMQ, but I am encountering errors. Below is the Docker configuration file I used and the error message from my configuration screen. Additionally, please confirm the RabbitMQ port settings.
