Same issue on : https://github.com/ttn-zh/ic880a-gateway/issues/66

On https://console.thethingsnetwork.org/ it is indicated not connected I redone the procedure 2 additional times but it has not changed

I don't know what to do to debug and find the problem. Could you help me ? thanks !!

That big of logfiles seems to indicate the concentrator is working correctly and it is the console that is not updating the status of the gateway correctly. This happens sometimes (unfortunately), so it cannot really be relied upon. For a better test, please use a lorawan module/sensor and send some packets, and check if you see them (either in the logs or in TTN).

Thank you for your reply. I will try to connect a sensor. Where is the log file that you indicate to me stored? Thanks !

I mean, the systemd log that you see in your own snippet. I think you can find it on /var/log/syslog and also using journalctl for the ttn-gateway unit.
