@JannesVolkens I'm not entirely sure what you mean by "the can bus I'm using". A can bus is just two wires, right? 
The resistor should also be as close to the transceiver as possible. I'm not sure where those integrated resistors you mention are located, but if they're too far away they will most likely not work, and they might even interfere with the reliable transmission.

But since you are using two nucleo's with two of these breakout boards, connected to eachother. Have you tried getting rid of all the other stuff that's in between? In other words: simply connect the CANH on board 1 with CANH on board 2 with some jumper wires, and do the same for CANL.
