X3 xDrive30e continuously stops charging Wallbox EASEE

Good evening, I’ve had the car with construction year 2022 since January and load it with a wallbox from easee so far without any problems. For one week the charging process is stopped constantly for uninventive reasons, sometimes immediately, sometimes after an x-percent charging condition. The display in the car shows: Charging process canceled, they contact the BMW service. Also the wallbox reports “Loading process canceled. I was at the BMW service today, where the error memory was read out, but the Feh ler did not appear there. On my wallbox also a Hyundai Kona is charged, but here without problems. My question is, does someone know the problem or has someone already had this error. Greeting KK
