Cube + Here2 CAN needs hot plug to work

My rover was working great but I have just changed out the electronics enclosure after the first one got cracked after a ‘driveaway’ incident. I tested all electronics after and all was good but now after rebuild I have to hot plug the Here2 to CAN1 before they talk. I see some people had this problem with Here3.
Any ideas please?
