Help configuring DNS over HTTPS Quad9

Installing and Using OpenWrt
1

My main source was: https://openwrt.org/docs/guide-user/services/dns/doh_dnsmasq_https-dns-proxy

I do things over luci so I install luci-app-https-dns-proxy. Cloudflare seems to work but I like Quad9 so I select Quad9 from the dropdown but it has alot of options to configure. For example, Cloudflare had listen port of 5053 preconfigured but Quad9 is just blank.

Do I delete the preconfigured Cloudflare entries and assign Quad9 to 5053? I mainly ask because I dug this up: https://quad9.net/news/blog/quad9-json-based-dns-service-retires-5-may-2025/

Which makes me think 5053 is not correct so I should type in a listen port of 443 for Quad9?

That is another protocol. You need 443 for dns-http-proxy

Use e.g 5054 as listenport or delete cloudflare and use 5053

You can simply edit this proxy instance and change the provider within.

Completely unrelated.
