In chirpstack i have in the gateway bridge a trace if integration/mqtt with the id of a gateway but i not see the gateway in chirpstack network server:

Does the MQTT topic prefix configuration match with what ChirpStack is expecting?

Thanks, but it worked by adding this lines to mosquitto.conf:
listener 1883 0.0.0.0
allow_anonymous true

Hi dear all!

I have the same issue. But i added this line to /etc/mosquitto/mosquitto.conf. and didn’t work for me

listener 1883 0.0.0.0
allow_anonymous true.

Please help me, i have had this poblem for several weeks.
