Only Blokada DNS and Cloudflare DNS work

realpixelcode commented 2 years ago

In Blokada, only Cloudflare DNS and Blokada DNS work. None of the other services listed work. In the browser, I get the error DNS_PROBE_FINISHED_BAD_CONFIG.

It does NOT make a difference whether "Encrypt DNS" is turned on or off.
It does NOT make a difference whether I set the DNS for all networks or for mobile/WiFi individually.
It does NOT make a difference whether my phone is connected to the internet via cellular network or WiFi.
The other DNS services are NOT offline. (For example, I'm using Digitale Gesellschaft's DoH right now in Desktop Firefox, and it's working fine.)
I have NOT set a custom DNS service in the system settings.
I have disabled "Private DNS" in the system settings.

I'm using Blokada 51.8.0 from F-Droid on Android 11.

I captured this log immediately after setting Digitale Gesellschaft DNS and trying to reach f-droid.org:

I've noticed the same issue on a Samsung stock Android 12 phone.
