End user here. I have an issue trying to program RDF800KN Siemens thermostats via MDT IP Interface SCN-IP000.03 with (or without) Secure enabled.
Trying to download - even partial download - the application results to error "Connection closed by remote device" after some seconds of programming activity
The device can be programmed without issues using my installer's USB Interface (2 different models actually), but it always fails with the IP Interface.
I can also program any other device in my home installation using the IP Interface, absolutely no errors there.
Any help or direction to a solution would be highly appreciated.
