I just changed my dns-over-https script to use quad9:

    # sudo /usr/local/bin/dnsproxy -l 127.0.0.153 -p 53 -u https://cloudflare-dns.com/dns-query -b 1.1.1.1:53
    sudo /usr/local/bin/dnsproxy -l 127.0.0.153 -p 53 -u https://9.9.9.9/dns-query

The bootstrap 1.1.1.1:53 was working but the DoH dns-query url was not. Hence my visit here :)

Edit: Now fixed, it seems. Quick work, if it stays up!

That's a biggie...

The 1.1.1.1 vpn still seems to be working
