Hi all, I am developing a chatbot using rasa. It works fine for the initial conversations. But, after some time the default fallback (“Sorry, Could’nt understand”) is obtained for all the input messages except “Bye”. After Bye , everything again starts working fine.Could someone please tell why this is happening and how to resolve it? Thanks in advance.

May be your Bot needs more training on different intents and scenarios, So use Interactive Learning for train your bot.

> **[Writing Conversation Data](https://rasa.com/docs/rasa/writing-stories/#using-interactive-learning)**

and Use ConversationPaused event Refer [https://rasa.com/docs/rasa/api/events/#pause-a-conversation](https://rasa.com/docs/rasa/api/events/#pause-a-conversation) or action\_restart at end of the conversations in the stories.md
