My device seems not connected to cloudflare DNS server. Also i have changed to another DNS provider but no luck. Also my internet speed become slow. Uninstalled reinstalled still no luck. This issue not apear on my tablet with android 8. Seems this issue from Blokada app itself.
I downloaded Blokada from Blokada.Org. My device is Oppo F11 with Official ColorOS 11 powered by Android 11.
Blokada version 5.10.1.
