🏷️ Feature Request Type

New Monitor

🔖 Feature description

I would like to be able to monitor DNS-Over-TLS and DNS-Over-HTTPS. Both are encrypted forms of DNS. I have a dns server that only responds to encrypted queries and I would like to monitor if it's up.

✔️ Solution

Add a DOT and DOH field to the DNS monitor.

❓ Alternatives

Theoretically I can monitor the ports, but that's not enough as the service could be intermitent

📝 Additional Context

No

DoH at least should be possible. If I am not mistaken, the dns2 module is used by the dnsResolve function here: https://github.com/louislam/uptime-kuma/blob/538f83205d75fdfc437bece61764e864ae90a5b0/server/util-server.js#L292-L293

And this module has baked-in DoH support. Here is the example code: https://github.com/song940/node-dns/blob/master/example/client/doh.js

I might try to tackle this and make a PR sometime later if I get the time to brush up on nodejs, but no promises.

This would be nice to have.

The DNS monitor is currently quite barebones and not really useful. If someone wants to improve upon this, our contribution guide can be found here https://github.com/louislam/uptime-kuma/blob/master/CONTRIBUTING.md

I'd love to have a way to monitor my Adguard Home DNS and see if it's still connectable.
