}

The report names no source files or tests. Start by reproducing the sequence using the journal details, including tcp://localhost:7883, the centor broker, and the Mosquitto_bridge message, then inspect the connection and retry logs. Done requires a confirmed cause for the displayed disconnect and a verified fix or a documented broker-side cause.
