Greetings!
This is my configuration, successfully tested at https://dnsleaktest.com:
name=“99_digitalcourage.conf”
description=“Digitalcourage (TLS)”
enable_tls=“1”
tls_port=“853”
ipv4=“46.182.19.48”
ipv6=“2a02:2970:1002::18”
ca_file="/etc/ssl/certs/ca-certificates.crt"
pin_sha256=“v7rm6OtQQD3x/wbsdHDZjiDg+utMZvnoX3jq3Vi8tGU=”
hostname=“dns2.digitalcourage.de”
I also set the attributes exactly the same as the other preconfigured servers, i.e. “0600” flag in the permissions for the file itself. I don’t know if this is important but it worked right away. I also named the file “99_digitalcourage.conf” which is the same scheme.
Hope this helps you,
Best regards
