Windows 11 DoH Configuration Not Working in Browser

Problem

I have configured the use of the DoH protocol in the network settings of Windows 11 and set the browser to use the system default secure DNS, but the browser still uses the DNS protocol instead of the DoH protocol. Only when I set DoH directly in the browser does it work successfully.

So, what’s the purpose of configuring DoH at the system level? Does only the system's own applications use the DoH protocol?

Steps to reproduce

1. Configure DoH in Windows Settings

2. Set Edge to Use the System Default Secure DNS

3. Open www.example.com in Edge and Use Wireshark to Verify if DoH is Being Used

    Hi @Eric,

    The option Use current service provider means DoH will only be used if the user’s OS DNS provider is known to support DoH. Please check if your OS DNS provider met the prerequisite. If not, you may explicitly configure a DoH provider in Choose a service provider.
