Hello,
we are not using mosquitto on the same server as chirpstack for many reasons. In our installation we are using a mqtt-broker running on another server, so I configured gateway-bridge for mqtt-pub and chirpstack for mqtt-sub to the external broker.
Everything works fine until I tried to upgrade from version 4.6.0 to version 4.9.0 of chirpstack.
Since this version, chirpstack seems to subscribe topic “$share/chirpstack/eu868/gateway/+/event/+” instead of “eu868/gateway/+/event/+” as it was before.
Because chirpstack-gateway-bridge is still publishing all the data to “eu868/gateway/+/event/+”, and topic “$share/chirpstack/eu868/gateway/+/event/+” is not existing, I don’t get any messages:
INFO chirpstack::gateway::backend::mqtt: Subscribing to gateway event topic region_id=eu868 event_topic=$share/chirpstack/eu868/gateway/+/event/+
chirpstack-1
ERROR chirpstack::gateway::backend::mqtt: MQTT error error=Mqtt state: Subscribe failed with reason ‘ImplementationSpecific’
Can someone please help me to solve this issue?
Kind regards
