Re: [mosquitto-dev] Socket error on client
|
Hi Matthew,
You want `try_private false`. If this is set to true, Mosquitto
bridges try to do some non-standard things that not all other brokers
like. These extra things are to forward on the retained bit, and not
return messages to the bridge that came from the bridge.
Regards,
Roger
