Tried to connect to query server via DNS-over-TLS and DNS-over-QUIC using Adguard VPN on Windows and iOS. My VPS has a domain name is has a SSL cert from Let's Encrypt.

skarz@skarz-ubuntu:~$ dnslookup google.com tls://waguns.net
dnslookup v. 1.8.0-8187
2022/10/28 16:52:49 [fatal] Cannot make the DNS request: getting connection to tls://waguns.net:853: connecting to waguns.net: all dialers failed: 4 errors: "dial tcp 104.21.91.178:853: i/o timeout", "dial tcp 172.67.177.29:853: i/o timeout", "dial tcp [2606:4700:3031::6815:5bb2]:853: i/o timeout", "dial tcp [2606:4700:3032::ac43:b11d]:853: i/o timeout"

Hi.

Well, what if you switch DNS server to, let say, tls://dns.adguard-dns.com ?
