Many thanks for sharing your solution. I’m not sure if I understand the underlying issue, is it a problem that the Mosquitto service runs as root user (probably something we should change)? Or is it the other way round that it usually requires some authentication, which Node-RED does not do by default? Probably there is some way choose a certain Mosquitto authentication method and configure this with Node-RED as well :thinking:.
