Default docker setup fail on DoT

[uber6]

Describe the bug
After running the default docker setup and visiting https://www.cloudflare.com/ssl/encrypted-sni and 1.1.1.1/help to test DoH/DoT, but fails at DoH/DoT when used with adguard.

To Reproduce
Steps to reproduce the behavior:

Docker run command:

docker run \
--name=my-unbound \
--detach=true \
--publish=53:53/tcp \
--publish=53:53/udp \
--restart=unless-stopped \
mvance/unbound: latest

Expected behavior
Get a pass for DoH/DoT

Error messages
Fail at DoH/DoT

This was posted in unbound-docker issue tracker and on multiple errors on my part, I closed it thinking it was actually working. After several more test, DoT fails on both links' tests.
