Status "never seen"

Hi everyone!

I hope you all are doing well. I am very beginner to LoRaWAN field. I have connected Dragino LPS8 Gateway. Also using Adafruit feather m0 LoRa node. The gateway is successfully connected but the node has a problem of connection. It shows the status “never seen” and no data is found in the data tab. I would request you to please assist me. Thanks.
