Running Debian Stretch on a Raspberry Pi configured to use DNS over HTTPS on my home network for a final project at school. Not very experienced with Linux, but managed to get it installed. When I checked to see if it was running properly I got an error message after entering “sudo cloudflared proxy-dns”
*Failed to start the listeners error="failed to create a UDP listener: listen udp 127.0.0.1:53: bind: address already in use"
Apologize if the picture doesn’t help. But I can get other screenshots if they are needed.
