RAK7268 cannot receive join-accept message

Setup:

  1. RAK7268 as gateway
  2. Arduino UNO R3
  3. LA66 LoRaWAN Shield

Server: The Things Network V3

I use Arduino UNO R3 and add the LA66 LoRaWAN Shield to send the join request message to TTNv3 and TTNv3 send the join-accept message to my Arduino UNO R3, but my Arduino UNO R3 do not get any join-accept message, and the RAK7268 gateway LoRaWAN Packet Logger do not see any join-accept message, do I miss some step on my RAK7268.
