Live TV Issue "Error Occurred : A server with the specified hostname could not be found."

I think I’ve narrowed it down to my pihole blocking live tv from working. When I switch the DNS server to 1.1.1.1, it works fine. I don’t see any blocked sites triggered in my pihole and have a thread here OTA Live TV not working on 2025.18.0 (hasn't worked in the previous either)

Would anyone mind changing their dns to 1.1.1.1 or 8.8.8.8 and verify if live tv starts working for them?
