Our QnA knowledge base is not connecting to our Azure Web bot

I am having issue with my Web bot in Azure. I have set up and trained my QnA KB and published. When I test the KB in QnA is works perfectly. I have set up a web bot in Azure by selecting SDK3 and C+ and then select Question and Answer. Once the application was live, I went in to the application settings and entered the QnA KB key, ID, and host name and save. When I go to test bot in the application panel, it is not answering questions based on our KB. It seems to be generically ask and answer questions like "what is your name" "nice to meet you" etc. It is not answered any of the questions we have programed in with answers
