Connect comms goroutine on state publish

I’m getting errors on state publish- here are the logs

The mqtt host is aws iot via ssl but the error does not occur when I’m connecting it to my local mqtt broker over tcp.

Along with this error, join accepts can’t reach the gateway bridge.

I’ve managed to get over all of this by using chirpstack gateway bridge 3.10.0, before the conn topic got introduced.

Does anyone have any idea as to why this happens? The logs came from 3.12.0 by the way

Could it be that the used TLS certificate is not authorized to connect or publish to that topic, and therefore the server-side terminates the connection?

Publishing and subscribing to the same topic is fine via mosquitto

Hi!

It seems that Im having the same problem. Did you solve it?

thanks in advance.
