unbound notice: sendto failed: Invalid argument

sololegends

I've been searching the internet and trying things for a couple days now. Gotten nowhere unfortunately...

The Issue

I have a new IoT VLAN setup recently but I can't seem to get DNS responding on it. Every time I attempt to query DNS from the VLAN I get the following in the DNS Resolver System logs.

Aug 13 13:55:23	unbound	74958:2	notice: remote address is X.X.77.100 port 61914
Aug 13 13:55:23	unbound	74958:2	notice: sendto failed: Invalid argument
Aug 13 13:55:23	unbound	74958:3	notice: remote address is X.X.77.100 port 37356
Aug 13 13:55:23	unbound	74958:3	notice: sendto failed: Invalid argument

I have DNS working just fine on all other VLANs in the network no problem. The IoT VLAN is the only one with the issue.

Troubleshooting Steps

Attempted with multiple different devices
Mirrored over firewall rules from a functional VLAN
Added an allow all to all rule in the IoT VLAN firewall
Disabled DNSSEC
Validated Unbound access lists
Disabled pfBlockedNG
Disabled all VPN clients and Servers within pfSense
Attempted pings between devices on the VLAN (successful)
Attempted allowing 8.8.8.8 through the firewall for clients to query for DNS, still didn't work. Which makes me thing it might not be an Unbound issue.

Network Information

Overview

Router/Firewall: pfSense
Wireless APs: Ubiquity Unifi (These APs tag the traffic with the appropriate VLAN based of the SSID) These APs are how all VLAN clients connect to the network.
Switches: TP-Link dumb switch
Other Info:

The VLANs in question are all using the same physical interface (Intel)
There are 2 OpenVPN Servers configured , only for different VLANs
All clients are assigned IP address by DHCP
- DCHP returns the X.X.Y.1 as the primary DNS server where X.X is the main Network octets and Y is the sub network octet (generally matching the VLAN ID)

Firewall

Working VLAN Firewall:

IoT VLAN Firewall:

Floating Rules:
All interfaces - Allow TCP/UDP - From * - To This Firewall - DNS(53)
