DMZ network cannot talk to LAN

i have one of our subnet dedicated to guests wifi , am using ubiquiti unifi controller and applying hotspot authentication 

it used to work before, but now i can only get IP address when i connect but it wouldn't redirect me to the hotspot captive portal

when i change the subnet to one from the LAN zone it work fine, its more like DNS is not directing the device to the hotspot

DNS setting is the same for all subnets, i also set a rule for DMZ to DNS server but it didnt solve the issue 

i set another rule for the DMZ to use any port with the unifi controller but didnt work too

its important for me to keep the guests in the DMZ zone, i dont want to change to LAN

 

best
