overnight search.brave.com is blocked?

[tl5k5]

Hello all,
I use search.brave.com all the time without any issues.
Overnight, at our small office, my admin VLAN can no longer resolve search.brave.com, but all of the other VLANs can.
I do have Geo and threat list aliases to block bad actors on firewall, but all the rules are applied equally across the different VLANs.
I've disabled the blocking rules just to make sure that wasn't it, but it made no difference.

Reporting/Unblound DNS/Detials shows to site is dropped.

Can anyone point me in the right direction...I don't normally have to troubleshoot this kind of thing.


Thanks!!
