can't select manual template with dns over https

The same problem.

I think this is not possible to select "On (manual template)" because there is no such option in Windows 11 Home Edition. It is only available in Windows 11 Pro version.

When you run as Administrator these commands:

netsh dns add encryption server=45.90.28.0 dohtemplate=https://dns.nextdns.io/ABCDEF autoupgrade=yes udpfallback=no

netsh dns add encryption server=45.90.30.0 dohtemplate=https://dns.nextdns.io/ABCDEF autoupgrade=yes udpfallback=no

(of course ABCDEF need to be replaced by your Configuration ID)

then you can type IP addresses in "Preferred DNS" and "Alternate DNS" fields and in drop down list "Preferred DNS encryption" become available so you can choose "Encrypted only (DNS over HTTPS)

but then... on https://my.nextdns.io when you logon and choose this profile it won't tell you

"All good!

This device is using NextDNS with this profile."

but instead:

"This device is not using NextDNS.

This device is currently using ”” as DNS resolver."

Its a shame for NextDNS Team that they provide instruction how to set DNS over HTTP without details that it works only in Windows Pro edition!

NextDNS client is nice - you can install it, provide Configuration ID and done but... if you have kids then they can easily just disable NextDNS client (right click - Disable) and bingo! No restrictions!

I have a yearly subscription in NextDNS but I will not renew it as this is not accepted that it is so easy to bypass settings for kids who even don't have administrative privileges granted by me on their PCs.

PS. If you ran above netsh commands you can revert changes by looking into registry in HKLM\SYSTEM\ControlSet001\Services\Dnscache\Parameters\DohWellKnownServers and there you see 45.90.28.0 and 45.90.30.0 keys that can be simply deleted.
