네트워크 문제가 아니라면 다음을 실행해 보세요. mqtt/bin/hiot 폴더 밑에 tmp, data 폴더가 있습니다. 각각의 폴더 아래에서 sudo rm 명령어로 파일을 삭제하시고 리스타트 해보세요.

말씀해 주신 방법으로 해결하였습니다. 하지만 문제가 하나 더 생겼는데요. 아래와 같이 DB에 리모컨 데이터도 넣은 후, "텔레비전 꺼죠" 라는 명령어를 말하니 문제가 발생하였습니다.

아래와 같은 에러 메세지입니다. @.@ STT : 텔레비젼 꺼줘 Jul 25, 2018 4:57:40 PM okhttp3.internal.platform.Platform log INFO: --> POST https://gateway.watsonplatform.net/conversation/api/v1/workspaces/86d2a7f6-70b1-4902-a3e8-924d7e09d290/message?version=2018-02-16 http/1.1 (414-byte body) Jul 25, 2018 4:57:40 PM okhttp3.internal.platform.Platform log INFO: <-- 200 OK https://gateway.watsonplatform.net/conversation/api/v1/workspaces/86d2a7f6-70b1-4902-a3e8-924d7e09d290/message?version=2018-02-16 (421ms, 475-byte body)

혹시 원인을 알 수 있을 까요?
