exception '2' (illegal data address), function '131'

[Chrunchy]

When starting the docker, the log starts showing fetch errors.
Any suggestions on how to troubleshoot?

I read that the modbus adresses could differ from the software versions, but not sure if this is the case.
I have a Air9 system as well.
