Spring AMQP + RabbitMQ 3.3.5 ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN

Question

I am getting below exception

org.springframework.amqp.AmqpAuthenticationException: com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED

Answer 1

For me the solution was simple: the user name is case sensitive. Failing to use the correct caps will also lead to the error.
