The URL you provided seems to be a local development server URL (localhost), which cannot be accessed from outside your own computer.

To access the RabbitMQ Management API, you need to replace "localhost" with the actual hostname or IP address of the server where RabbitMQ is running. Additionally, you may need to provide authentication credentials (username and password) to access the API.

Once you have the correct hostname/IP and authentication credentials, you can make a GET request to the following URL to retrieve information about queues:

http://<hostname or IP>:15672/api/queues?page=1&page_size=50

Make sure to replace <hostname or IP> with the actual hostname or IP address of the RabbitMQ server.

Note: The RabbitMQ Management API is only available if you have enabled the RabbitMQ Management Plugin. If the plugin is not enabled, you won't be able to access the API
