    Somehow I woke up to the DNS not working.
    I’ve removed the network configuration on my macbook, restarted, set it up again but something is wrong

    Still unusable. Is the paid version faster?

    MacOS
    Macs come with the networksetup command line tool that allows you to configure the network settings. It can also be used to change the nameservers by using it with the -setdnsservers flag. Open your terminal by going to the spotlight and typing “terminal” and run:

    sudo networksetup -setdnsservers Wi-Fi 185.228.168.168
    That will force the Wi-Fi to go through CleanBrowsing (185.228.168.168). If it works, you won’t get any warning or error in the terminal and you are all set. As a bonus point, you can run the chflags command to block anyone from changing the nameserver via the graphical user interface:

    sudo chflags schg /Library/Preferences/SystemConfiguration/preferences.plist

    This worked better. Seems to be the app that is causing issues

    Where are you located and your ISP? Mind sending the output of:

    traceroute 185.228.168.10
    or

    tracert 185.228.168.10 (if you are on windows).

    So we can see what is going on? And the other results means you are going through IPv6, not the configured IPv4 DNS.
