Not sure if I made some mistake or something just don't working.

I have a domain (example1.com) which I'm using as a blog (port 80 and 443 are used)
I've created _acme-challenge (TXT) on my domain and now DNS server admin panel is served via https.
I want to use DNS over TLS since 443 port for DoH is used by the blog.
When I try to use tls://example1.com as a DoT it's not working,
DNS server itself works.

Did I miss or doing something wrong?

Version of AdGuard Home server:
- Version: 0.104.1
How did you setup DNS configuration:
- Router
Operating system and version:
- Ubuntu 20.04

Expected Behavior

Able to use tls://example1.com

Actual Behavior

DNS apps on android say that it's invalid address

Additional Information

I want to use my blogging domain:853 as a DoT

You know, in your case I'd suggest using nginx as a reverse proxy that serves both AdGuard Home and your blog.

For instance, you could serve AdGuard Home from a location (example1.org/adguard or smth like that):

Regarding the original question - use telnet to check if port 853 is open.
