Communication Error Homematic Bridge

Hi,

i am trying to connect openhab to my HomeMatic CCU3 via the appropriate binding, but i only get: communication error: Unknown XML-RPC tag: title. I did some research and found forum post which stated, that this error occurs because the newest CCU versions won’t support BINRPC, but since 2.4.0M6 XMLRPC would be supported. So i upgraded to the latest version but had no success - still the same error. Any ideas? Maybe I forgot to configure something?

Versions:
CCU3 (piVCCU): 3.43.15
OpenHab2: 2.5.0.M1
HomeMatic Binding: 0.11.0.oh250M1

Thanx
Frank

Found the answer by myself. Authentication was enabled in CCU configuration. Disabling it did the trick.
