Facing issues with connect with AWS IoT core for LoRaWAN.

We are using CloudGate Options gateway for connecting to AWS LoRaWAN. We have installed basic station for it. Also we have configured it with details which we got it from IoT core Lorawan gateway registration

but when we checking on the gateway logs we could see that 2023 Sep 11 05:12:04.289 station: [TCE:VERB] Connecting to MUXS... 2023 Sep 11 05:12:06.391 chaser [3443]: <1> chaser.c:hw_watchdog_kick(660) - *** barks to the HW dog *** 2023 Sep 11 05:12:06.526 station: [TCE:VERB] Connected to MUXS. 2023 Sep 11 05:12:06.528 station: [AIO:DEBU] [3|WS] Server sent close: reason=1006 2023 Sep 11 05:12:06.529 station: [AIO:DEBU] [3] ws_close reason=1006 2023 Sep 11 05:12:06.531 station: [AIO:ERRO] Recv failed: SSL - The peer notified us that the connection is going to be closed 2023 Sep 11 05:12:06.533 station: [AIO:DEBU] [3] WS connection shutdown... 2023 Sep 11 05:12:06.535 station: [TCE:VERB] Connection to MUXS closed in state 4 2023 Sep 11 05:12:06.536 station: [TCE:INFO] INFOS reconnect backoff 10s (retry 1)

Please see the screenshot for aws logs. It is showing Gateway connection getting closed after 2-4 seconds. How can we resolve this issue?
