Art-Net DAT not showing ArtPollReply from custom device

Hi,

I am testing my custom Art-Net receiver against Touch Designer, using version 099 2021.15240 on Windows 10. The DMX Out CHOP is working fine, but I am unable to get my Art-Net receiver to show up in the Art-NET DAT table. The goal would be to automatically configure the DMX Out CHOP’s Network Address to use the discovered Art-Net output’s unicast IP address.

Using wireshark, I can see that TD sends an ArtPoll packet, and my device sends an ArtPollReply. The poll reply looks fine in wireshark, but why does it not show up in the Art-Net DAT table viewer?
