[SOLVED] Some DNS servers are working, some not

Edit: The issue was that I used the wrong IP. For example: 9.9.9.9 instead of dns.quad9.net (which is the address for DNS over TLS).

Hello,

I am configuring my system to work with DNS over TLS.
I am using systemd-resolved and NetworkManager for this.

The problem is that some DNS servers are working and some are not.
The servers which are not working are from "smaller" groups, like dns.watch, dismail, disforge.
The servers which are working are from Cloudflare, Google, Quad9.

My resolved.conf:

[Resolve]
DNS=9.9.9.9
DNSOverTLS=yes
DNSSEC=yes
FallbackDNS=1.1.1.1
#Domains=~.
#LLMNR=yes
#MulticastDNS=yes
#Cache=yes
#DNSStubListener=yes
#ReadEtcHosts=yes

What is the issue?

Further question: How I can test if DNS over TLS is working?

Thank you for your help.
