RFXtrx433E via RFXCOM Binding stays Offline - Windows Server 2008R2

Hi openHABies,

another problem from a newbie - trying to get RFXCOM binding to work.

I got a RFXtrx433E, connected to the Windows machine (Win Server 2008R2), RFXMGR working fine - receiving and sending commands no problem.

Auto-Discovery via PaperUI works fine as well, RFXtrx433E is found and added to the Things List.

Unfortunately, it stays offline.
Logfile says:

I tried to manually add it via Serial Port (COM3) where it stays online, but doesn’t show any new items in Inbox when i press a remote button.
Tried to de-install the FTDI Windows Driver, but same problem, Bridge stays offline.
Still, direct communication from RFXMgr works fine.

Anyone has any ideas here?

Thanks for your feedback!

Best regards,

Problem seems to be solved - after the third try manual adding worked!
