Alternatively try the Granny charger that came with the car.Have the wife lock the car and walk away for 1 hour.
Unlock the car with the fob while listening for the charge door to unlock and a similar noise for the charge port actuator to "unlock".
Connect the charger. She should hear the charge port actuator lock the charger to the car. If not, there's a problem (possibly a stuck locking actuator pin).
Wait a few seconds and both the car and charger should indicate charging. If not, it is either the charger or the car (obviously).
Do you know anyone else with an EV and charger? Could you try using their charger to determine if the problem is your charger or the car?
If the car charges with DCFC then the problem is most likely with the Chargepoint charger although some have had rare instances of AC charging failing and DC charging working.
A stuck actuator locking pin might get unstuck with iterations of locking/unlocking the car without the cable attached.
