Hey! So I had the same issue last week, and it drove me nuts lol. Turns out, the tproxy setting on iPad is kinda hidden. You gotta go to Settings > Wi-Fi, then tap the little "i" next to your connected network. Scroll down, and you should see "Configure Proxy." Tap that, and you can switch it off.
If it’s not there, maybe try restarting your iPad? Sometimes settings glitch out. Hope that helps!
