RAK Gateway never seen

Hello everyone. I am trying to connect RAK7289C gateway to Chirpstack and it is not seen in the web server. I tried to change Backend types multiple times (Semtech UDP/ MQTT) and wrote the region and gateway id in the gateway bridge configuration file but it still is not working. Sending images below.

I would be very grateful for the help

To confirm:

  • Are you using ChirpStack v3 or v4?
  • Is your MQTT broker running on your gateway (because you configured as IP address)?
