[skapytek]

Hi,
ive set up and configured my server but for example edge browser says "Please check whether this is a valid provider."
My dns server ive set up and im trying to use is: https://adfreedns.eu/dns-query

I cant find any error, maybe you can help me.

Thanks!

Thanks for the post. I tested the DoH URL and it seems to be working as expected with no issues. Tried it with Firefox and it worked well.

The DNS Client is also able to query it: https://dnsclient.net/#https%3A%2F%2Fadfreedns.eu%2Fdns-query/google.com/A/HTTPS/true/

You need to configure the Advanced Blocking app though since its using default example config: https://dnsclient.net/#https%3A%2F%2Fadfreedns.eu%2Fdns-query/example.com/A/HTTPS/true/

You cannot setup Block Page app and DoH on same IP address since both require the same ports. You will need to host a web server with default website and self-signed cert then configure the blocking settings to use the IP address of your web server.
