DRAGINO LoRaWAN showing never seen on Chirpstack

I am uding Dragino LoRaWAN gateway with Semtech-UDP to setup with chirpstack, It always shows never seen, i have checked all the FW permissions and also the region settings, can someone help me to solve this problem.
I am using it in a docker enviroenment.

I use Dragino LPS8, LPS8v2 and DLOS8 gateway.
My ChirpStack v3 and v4 show Seen/Last Update ok.

Are you able to see any data inside Devices > Events / Frames?

No I can’t see any data inside too.
I am using LG 308

Are you using OTAA or ABP for the devices?

For OTAA, the device must be able to join LoRaWAN network before abling to send Uplinks as in your photo.

Seems you have a lot of devices in your photo.
