Working V4 server failed and no longer starts - error: Setup MQTT Integration

1

My Chirpstack V4 server has been running since the end of Nov 2022 without any issues and then today I saw no messages being received from it on my mqtt broker.

I have rebooted but see in the logs an issue caused by setup mqtt integration.

I am at a loss as no config changes have been made and I cannot see what is wrong.

Help very much appreciated!!

Look into the log; it’s the place to find reasons for any errors.
