Is it possible that 192.168.0.202 is the IP number of a non-local server 
running a RabbitMQ broker with different credentials?

Check the output of "rabbitmqctl list_users" and double-check that the 
usernames that you expect appear. Also check the output of "rabbitmqctl 
status" and retry the test using the hostname (part after the @) instead 
of the IP number.
