Hello, I also encountered this problem, maybe Adguard is blocked in our country.

Yes, it seems to be blocked. We have no idea why to be honest, haven't received anything from them.

Could you please reach out to the ISP and ask what's the reason for that?
Also, what about other popular DNS resolvers? Do Quad9, Cloudflare DNS or Google DNS work?

I contacted my ISP - Citynet and they told me in an email that no restrictions have been put in place to block AdGuard.

I tried using AZ residential proxies to test it on our side and it seems that all major DNS resolvers are blocked in Azerbaijan: https://dns.google/dns-query and https://1.1.1.1/dns-query also do not work.

I wonder could it be that it only blocks DoH and not DoT/DoQ?
