I have a browser using DNS over HTTPS. This service uses cloud flare service so when I go to https://1.1.1.1/help, I get the following.

But if I turn on private DNS using the bellow settings for cloud flare "using DNS over https (DOH) changes to yes. These are 2 different protocols and should not affect each other.

Any ideas why this occurs

You posted that a while ago. Any idea why this occurs
Also, you've shown that you don't understand what DNS is.

I did not post this issue. Good to see you are monitoring all my posts.

it appears you don't know what DNS is otherwise why didn't provide an answer?

let me help you. DNS stands for domain name system. This is the server's that resolve domain names like www.google.com and resolves it to an I.P. address.

the 2 protocols discussed are D.O.H. DNS over https and D.O.T. DNS over T.L.S. both are separate ways of encrypting DNS requests where you phone is connecting. However Samsung A50 phone only allows DOH to work when DOT is active. THIS IS ABSOLUTELY INCORRECT.

Uh, you are the one who doesn't understand the protocols you're discussing.
Yeah I know what's DNS and DoH and DoT, thanks. Your issue is that if you use Private DNS, you benefit from DoH protections. It's not an issue, it's the intended behaviour. If your ISP doesn't provide DoH or DoT protections, you won't get them without using a private DNS. Now please learn what you're talking about before telling me I don't. This is the second time this occurs, and the second time your accusations backfired.

The problem is that DOT sends all encrypted data to a single port. Port 853 and tuber problem with that is public wifi can easily block that port resulting in no internet.
however DOH runs over https the same service used to go to https://www.google.com, so it's impossible to block without turning all internet service off. Both protocols can run together but the problem I'm reporting is DOH doesn't work but https to web sites does work.
