Can't connect to custom nrf52 board with J-LINK

We come from here : 

https://devzone.nordicsemi.com/f/nordic-q-a/35180/error-with-nrf52dk-and-mac-os-hs

Now, i have a new development kit and i can program it but now i have a problem with the J-LINK connection, i cant connect with my nordic 58323 custom board 

I have tried from j-link, and j-link commander, and nrfjprog --recover, nothing works :( 

I have tried with a few usb wires too, and a few laptops with differents environments (windows, mac)

Here is the  nrfjprog --recover log :

nrfjprog --recover --log

nrfjprog version 9.7.3
