Issue with using python XmlClient

Gurux.DLMS

I've just started to use python's xmlclient and I used same cmd arguments as in "normal" gurux client. The problem is, when it starts to read Clock, there's "Data send failed" and it stops reading. Same issue happens when I added -x argument with GetClock.xml . Logs are below:

And there's just exception at end:
raise TimeoutException("Failed to receive reply from the device in given time.")

What am I doing wrong? Cmd line (which worked in normal gurux client) below:
python main.py -r ln -c 1 -s 1 -h <ip> -p 3294 -i WRAPPER -t Verbose -a Low -P 12345678 -C None -d DLMS -L MCS -v 0.0.43.1.1.255 -o "GetClock.xml"
