VR not pair in PC and mobile phone

hello, I have a quest 2 I did everything to pair and start working with quest 2, my quest 2 is paired on the phone, and it could be cast but it doesn't work and is not paired like the below image. 

 after that, I tried to pair and connect with a laptop and it also it didn't work, I used straight connection with lan it doesn't work and also I get messages when I want to use wifi( Im using the same wifi) 

I have no idea what I should do.
