It's true that network recovery interval is currently used

 * Before attempting the recovery
 * Between recovery attempts that throw ConnectException

Unfortunately, it's not possible to tell what may be going on from this message.

Define a custom exception handler that overrides handleConnectionRecoveryException
and inspects the cause. Also, see what may be in RabbitMQ log.
