Hi,

Would this happen to be 2 of the RB-See-394?

If so, the manufacturer does mention the following warning:

@manufacturer

When you use more than two CAN Bus Shield in one net, you should take the impedance into consideration. You should either cut P1 in the PCB with a knife, or just remove R3 on the PCB.

This may be related to the issue you are having.

For more help, it would be best if you would provide some pictures showing clearly all components and connections. You can attach pictures to your reply in Full editor mode.
Sincerely,
