Usar DNS over HTTPS con Cloudflared en Raspbian

Question

Hace algún tiempo he logrado instalar entre otras aplicaciones el Pi-hole en mi Raspberry Pi 4.

Después de ver y analizar diferentes bondades, me quedé con la posibilidad de configurar DNS Over HTTPS directamente en la raspi y que se integrara de forma natural con Pi-hole.

Por algún motivo el DoH se escapa a mis capacidades, ya que siguiendo el manual oficicial no soy capaz que el sistema funcione

Mi versión de Cloudflared es:

sudo nano /etc/default/cloudflared

# Commandline args for cloudflared, using Cloudflare DNS
CLOUDFLARED_OPTS=--port 5053 --upstream https://1.1.1.1/dns-query --upstream https://1.0.0.1/dns-query`

sudo nano /etc/systemd/system/cloudflared.service

[Unit]
Description=cloudflared DNS over HTTPS proxy
After=syslog.target network-online.target

[Service]
Type=simple
User=cloudflared
EnvironmentFile=/etc/default/cloudflared
ExecStart=/usr/local/bin/cloudflared proxy-dns $CLOUDFLARED_OPTS
Restart=on-failure
RestartSec=10
KillMode=process

[Install]
WantedBy=multi-user.target

sudo nano /etc/cloudflared/config.yml

proxy-dns: true
proxy-dns-port: 5053
proxy-dns-upstream:
  - https://1.1.1.1/dns-query
  - https://1.0.0.1/dns-query
  #Uncomment following if you want to also want to use IPv6 for  external DOH lookups
  #- https://[2606:4700:4700::1111]/dns-query
  #- https://[2606:4700:4700::1001]/dns-query

sudo systemctl status cloudflared

¿Alguien puede decirme donde tengo el error? ¿por qué el sistema no funciona?

En el Pi-hole tengo las DNS apuntando a 127.0.0.1
