Manta m8p v1.1+ cb1 errno 100

[Skipperin0]

I am currently trying to make canbus work on my bigtreetech m8p with cb1 and the sb 2209. While following online guides I am able to follow every step succesfully (so I think) untill it's time to run the command to get the UUID: ~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0
When I run this command I get this response:
biqu@BTT-CB1: ~/klipper$ ~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0
Traceback (most recent call last):
File "/home/biqu/klippy-env/lib/python3.9/site-packages/can/interfaces/socketcan/socketcan.py", line 679, in _send_once
sent = self.socket.send(data)
OSError: [Errno 100] Network is down

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/home/biqu/klipper/scripts/canbus_query.py", line 64, in

File "/home/biqu/klipper/scripts/canbus_query.py", line 61, in main

raise can.CanError("Failed to transmit: %s" % exc)
can.CanError: Failed to transmit: [Errno 100] Network is down

I am obviously missing something, but I can't seem to find out what I'm doing wrong. Is there anybody who can point me in the right direction?
