chirpstack-gateway-bridge 3226e542433e (Cant find mqtt broker)

[ccall48]

gateway bridge not connecting in latest version.

I double checked my configs and even hard coded the gateway bridge mqtt settings and it always tried to connect to localhost:1883 no matter what I set this to ( it should be going to my container as set in settings tcp://mosquitto:1883 for my server). I was pulling hairs trying to get this to work - I ended up dropping back to version 4.0.3 and it connected and worked straight away with exisiting config.

all other services connect fine, just errors with gateway bridge component.

errors with latest gateway-bridge image 3226e542433e
