I switched to 2.1 and upgraded my QNAP TS212 controller connected to my KNX installation.
Unfortunately I don't get a reliable setup up and running. I persistantly get this KNX.log error message:

Service failed
org.openremote.controller.protocol.knx.ip.KnxIpException: Service failed, no ACK

followed by

Service failed Socket is closed

Everything was running smoothly over weeks before. So I tend to switch back to the working setup.

Hi Jim,

I have the same problem when I switched to the latest controller.
Have you managed to solve it?

Hi Gideon,

if I remember correctly, I just made a stupid mistake and forgot to enter the correct knx IP address in the file.
See here under "configuration of system".

Hi Andi,

Thanks for the reply.
Not sure whether I have the same problem then. Checked the config file and I have the correct ip address. Also the same knx command works several times correctly and then it suddenly crashes.
I have also tried tried to specify no ip address in the config file so that the controller uses the first available knx interface. But I still get the same error.
Maybe I just go back to earlier controller version, which was working fine.

Best wishes
