MQTT host server discovery

Hi, I have a question regarding MQTT host server discovery from a Tasmota SONOFF device.

Compiled the code with USE_DISCOVERY and MQTT_HOST_DISCOVERY enabled in the source code.
Using the mosquitto MQTT broker.

The device is not able to discover the MQTT server, but if I use the console command MqttHost to set the IP of the MQTT server it works.

Any advice in this regard?

This looks like a question for the Home Assistant forums.

Or the tasmota forum, it appears to nothing to do with node red at all.
