안녕하세요,

최근 질문과 같은 질문으로 보여,
링크 걸어 두겠습니다.

[\[WizFi310\] MQTT 사용 관련 문의입니다.](https://forum.wiznet.io/t/WizFi310-MQTT-%EC%82%AC%EC%9A%A9-%EA%B4%80%EB%A0%A8-%EB%AC%B8%EC%9D%98%EC%9E%85%EB%8B%88%EB%8B%A4/3519/2) [Wi-Fi 모듈](https://maker.wiznet.io/c/korean-forum/wi-fi-ebaaa8eb9388/135)

> 안녕하세요 로그를 보니, 해당 연결은 Azure에서 MQTT 연결을 끊고 있는 것으로 보입니다. 원인은, User name, password, Client ID와 같은 인증 관련 정보들이 틀린 것 같습니다. 위 내용이 맞는지 확인 부탁드립니다. 위에 입력해주신 내용으로 보아, username은 PVT-HUB.azure-devices.net/Wizmega_test/api-version=2016-11-14 password는 SharedAccessSignature sr=PVT-HUB.azure-devices.net%2Fdevices%2FWizmega_test&sig=K5fydK0YBW1b6AYzBfinEUbd8gdGKTWY5QK0Rs2kPMg%3D&se=153544470 인것으로 보이는데, Client ID가 입력되지 않았습니다.

감사합니다.
