2 CAN-BUS Shield together via 2 jumper wires not working

Hello, i’ve followed this tutorial (https://wiki.seeedstudio.com/CAN-BUS_Shield_V2.0/) in order to install a communication between my to can bus shield V.2 Seeed.
It wasn’t working so i tried to cut one of the P1 (see bellow). RX and TX are not blinking too (see bellow) . I’m using code from the seeed website. ( send and receive check )

I have “Can init ok” in the serial monitor but nothing else.
