The "mobiledevlist" function cannot detect the mobile device?

Env:

windows10

Iphone7/apple ios 12.2

matlab2020b

latest MATLAB Support Package for Apple iOS Sensors

Matlab Mobile 8.3

Issues:

Both the computer terminal and the mobile terminal can be used independently, and both are on the same local network. The computer is connected to the home router through a network cable, and the mobile phone is connected through the wifi of this router, but the computer and mobile phone are still unable to connect and communicate. How can I solve it? （The phone has been configured as prompted）
