Home Assistant - AdGuard Home - UniFi VLANs

I’m encountering an issue where AdGuard only functions properly on the network/VLAN where Home Assistant is located, but not on my other VLANs, such as my main LAN. I’ve configured a static IP for Home Assistant both in UniFi and within the Home Assistant settings. Additionally, I’ve set my WAN DNS server to Home Assistant and configured individual network DNS servers to point to Home Assistant. However, AdGuard is only effective on the VLAN where Home Assistant resides, despite Home Assistant having access across all VLANs. There are firewall rules in place blocking inter-VLAN communication, but Home Assistant has been granted access across all VLANs. Any insights on resolving this issue would be appreciated.

Showing only clients within the 10.0.2.1 VLAN are picking up AdGuard:

Did you every figure this out? I’m in the same boat.
