Lopy4 nanogateway loses some downlinks from TTN

Hi, I am trying to receive downlinks from TTN but sometimes I miss some of them, I am using the BL072Z board as node and LoPy4 as the gateway, uplinks work ok, the issue is with the downlinks, the TTN terminal shows the downlink was received but it is not received by my node, thanks
