HomeKit CoProcessor Authentication Failed(BLE)

Hi everyone,
I'm developing some HomeKit Accessory currently, i.e., a bulb. Before I was testing with no authentication and the device successfully paired with my iPhone.
After a read certification from CoProcessor, I got a LOG as following:
"Rejecting request: Session is terminal."
With such error accessory terminated the BLE link and abort pairing. I found such log in GetProcedure() and still not clear the reason.

Could anyone kindly help this Rookie?

Thanks so much.
