Audi Error switch phases: modbus: exception '3' (illegal data value), function '6'

Hello everybody,

So nice to see when I have a question others are helping to fix it. My problem.
I have a Alfen "wallbox" for my Audi E-tron with 95kW.
Evcc is connected to HA. The Alfen is connected with the network with a cat6a cable and also a cable for the P1 (energy meter).
This is the error I get: Audi Etron 55: switch phases: modbus: exception '3' (illegal data value), function '6'

So what is it that I don't see?
Thank you,

Greetings Peter

I found the problem!
I setup the Alfen charger as and only as a 3 phase charger, when I changed this that it could switch between 1 and 3 phase everything was up and ready.
