Hi,
I have been trying to download a few KNX devices using a LogicMachine (LM) as an IP interface, but it fails every time. The weird thing is that when I replaced the LM with an Apricum IP Interface, I had absolutely no problems downloading.
Here is what I have tried so far to troubleshoot:
For further context, I am using ETS 6.4.1. I have attached the downloading telegrams as an export from ETS Diagnostics to this post to help with troubleshooting, some telegrams are flagged with error but I do not know why
Could this be a hardware issue with this specific unit? Has anyone experienced something similar or has any suggestions?

Here is what I have tried so far to troubleshoot:
- Firmware rollback: I thought it could be an issue with the new firmware (20251204), so I tried reflashing the LM with an older firmware version (20211215), but the problem persists.
- Network change: I tried using a completely different network setup, but nothing changed.
