Hi,
I just installed Chirpstack OS (full image), on my Raspi 3.
Eveything works fine at first:
- I can see the gateway ID in chirpstack concentratord config
- I can see the stats, and uplink message when using mosquito
The issue appears when I add the Gateway in the UI (port 8080).
Then a /config message is received, the MQTT logs stop, and concentratord keeps restarting, see this log:

If I delete the gateway from the UI, and reboot, I can see the MQTT messages correctly again (stats, uplink).
I'm really sad, I was so eager to start playing with the devices etc :(
Thanks for your help!
