Quad9 users: DNSCrypt configuration has changed

[davidemyers]

If you are using Quad9 for encrypted DNS be aware that the symbolic names used by dnscrypt-proxy have changed. This unfortunate change might cause all DNS queries to start to fail for your AlgoVPN clients.

The name quad9-doh-ip4-filter-pri has been changed to quad9-doh-ip4-port443-filter-pri, and quad9-doh-ip6-filter-pri has been changed to quad9-doh-ip6-port443-filter-pri. You'll need to change these names in /etc/dnscrypt-proxy/dnscrypt-proxy.toml and restart dnscrypt-proxy.
