when I started my core & nlu servers with the endpoints referring to localhost, I was getting the same error I got in my interactive trainer on my regular REST call which was working previously too… Once I shifted it back to rasa\_nlu:5000, my regular calls are working, but the interactive training is getting the error that the service rasa\_nlu is unknown.
