Hello,

You have to check the following:

Can bus connections: STM32F413ZHTx Nucleo Board + your external transceiver that are connected to another CAN node through CAN bus.
If you are using CAN in normal mode, HSI clock is not recommended for CAN communications. Please use external precise crystal.
Did you tried first to use loopback mode before going to normal mode? This to discard all issues related to your HW. Please refer to the example provided in STM32F4 Cube under the path: \Projects\STM324x9I_EVAL\Examples\CAN\CAN_LoopBack
