Thanks for your direction but I am still having issues in getting Chirpstack to send application topics to my external broker.
When I modify chirpstack.toml (see below) Chirpstack does not appear to make a connection to my external broker, I have checked the chirpstack and mosquitto logs but can see no error message. I have shown below the chirpstack.toml log showing when a client join request is made to see if this sheds any light on the problem.
If I modify the chirpstack-gateway-bridge.toml with my mqtt credentials I do see and receive published topics.
I am obviously doing something wrong, your help really appreciated.
