Unable to SuperCharge unless I reboot MCU issue

Last five times I have SuperCharged I had to reboot my MCU to get it to charge?
The screen would display "Charge Port Open" but no charging, no green light ring.
Tried other stalls and the same issue, but charges after a reboot.
Anyone with this issue?

Your MCU is failing.. hopefully you know your options and next steps. If not, the next poster will tell you

I had similar problems regularly with MCU1. Never happened again after upgrade to MCU2.

I never had this happen with MCU1 but it has happened about 5 or so times in almost 1 year since i got MCU2.
Only thing i can do is unplug, do a brake pedal reboot, and plug back in and it works.
