The error message you provided indicates that the RabbitMQ server failed to start due to an error. There could be many reasons why this happened, but some common causes include incorrect configuration settings, network connectivity issues, or insufficient system resources.

To troubleshoot this issue, you can check the RabbitMQ logs for more details on the error. The logs are typically located in the /var/log/rabbitmq directory. Look for any error messages or stack traces that might indicate what went wrong.

Another thing to check is whether all the required dependencies are installed and running. For example, RabbitMQ requires Erlang to be installed and running on the system.

If you're still having issues, it might be helpful to provide more details about your setup and the steps you've taken so far to try and resolve the issue.
