Is it possible that you are having the same problem I am? Complete DNS failure after frequent switching between WiFi and Mobile networks. I use Brave also and it reports messages like that.
Also, while it won’t fix the problem, have you Disabled “Secure DNS” in Brave’s settings? If your DNS request are going through Blokada, by default they are already secure and disabling DNS over HTTPS in Brave significantly speeds up page load times!
In Brave:
- Click the 3 button menu
- Click “Settings”
- Click “Privacy and Security”
- Click “Use secure DNS”
- Then turn off the toggle to “Use secure DNS”
