STM32F446RE, firmware V1.25.0, HAL driver for CAN doesn't generate rx interrupt

I've tried numerous of configurations, initialized pins in different modes, but CAN doesn't reach IRQ handler...it should work after "HAL_CAN_ActivateNotification(&hcan1, CAN_IT_RX_FIFO0_MSG_PENDING)" according to library documentation....the driver initializes fine, and I'm able to send messages succesfully...however RX never generates an interrupt..am I missing something

Note: I tried both loopback mode, as well as normal

    Ok, it seems that you have to configure filter, it won't pass all messages as default
