RFM95 Downlink Problem

Hi, Iam using RFM95 as lorawan transmitter to the RAK Lorawan Gateway. Uplink data is successfully transmitted, but not with downlink data, apparently it has issue with RX_Timeout that keep appear after successfully transmitted an uplink Data. I tried send downlink data to node but failed due to this Issue.
here the debug result:
Mbed LoRaWANStack initialized

Any solution would be appreciated
