OTAA Join Request Not Receiving Join Accept on ChirpStack v4

Hello everyone,

I’ve set up ChirpStack v4 in a Docker environment and am testing OTAA join for my LoRaWAN node (RAK811). I can see the Join Request coming into the ChirpStack UI, but there is no Join Accept.

Setup details:

  • ChirpStack version: v4.6.0
  • Region: IN865
  • Device: RAK811 OTAA node
  • Gateway: RAK7244, connected via Semtech UDP
  • Time sync: Enabled (GPS on gateway)

Steps already tried:

  • Verified DevEUI, AppEUI, AppKey
  • Device Profile matches correct LoRaWAN MAC version
  • Gateway shows as “connected”
  • Application logs show no obvious error

Would appreciate any guidance or similar experiences. Happy to share logs if needed (after redaction).

Thanks!
