GXDLMSTranslator help needed (python)

Hello,

The "Netz Noe" uses some strange encrypted mbus communication. I was able to decrypt the payload. but i cant get the XML of the decrypted APU. The Online Transltor at https://www.gurux.fi/GuruxDLMSTranslator can convert it to xml.

Here is the used code and the output from Online Translator:
tr = GXDLMSTranslator(TranslatorOutputType.SIMPLE_XML)
daten = recv(ser).hex()
if (daten == '' or daten[0:8] != "68010168"):
continue
print ("Daten: ", daten);
systemTitel = daten[22:38]
frameCounter = daten[44:52]
frame = daten[52:560]

frame = unhexlify(frame)
encryption_key = unhexlify(evn_schluessel)
init_vector = unhexlify(systemTitel + frameCounter)
cipher = AES.new(encryption_key, AES.MODE_GCM, nonce=init_vector)
apdu = cipher.decrypt(frame)
print("APDu: ", apdu.hex())
print("MessageToXml: ",tr.messageToXml(apdu.hex()))

--> Invalid DLMS framing.
