Cam Pan V2 cannot connect

I cannot connect to my cam-pan-v2. It was working fine. I think I have done everything:

Tried turning off 5G radio on router
Tried turning on Guest access and connecting to it (2.4G only)
Factory reset - hold setup → apply power → wait several seconds
Updated firmware → LED turned purple
Tried another iPad
Tried with and without memory card
Deleted camera from app

Red LED never flashes, just solid red

No sign of life from camera.
