Odd. The connection should recover automatically.
- What version of node-red are you using?
- What version of node-js are you using?
- What broker are you using and where is your broker? (local? Lan? Cloud?)
- Have you specified a client id in your MQTT config node? If so - is this necessary? is it duplicated elsewhere?
When it is disconnected, do you wait at least 1 minute for reconnection?
