When I try to use a TLS server, ADH fails to test the upstream DNS or respond to a client request.
Test upstream DNS Servers
Code: Select all
tls://94.140.14.140
tls://dns.adguard-dns.comUsing default bootstrap DNS servers:
Code: Select all
9.9.9.10
149.112.112.10
2620:fe::10
2620:fe::fe:10When I test the DNS server, ADH displays an error like this:
Server "tls://94.140.14.140": could not be used, please check that you've written it correctly
tls_test_error
However, when I try an HTTPS server, the connection is successful (https://94.140.14.140/dns-query).
Specified DNS servers are working correctly
https_test_success
What bugs me more is that I have two other ADH setups with TLS servers and the tests are all successful, with no problems.
Only this instance running on Mikrotik fails with TLS servers.
I haven't configured much of anything yet. Everything is running with the default configuration.
I thought this was a firewall issue, but could not find any rule that would drop AdGuard DNS requests.
This is my current firewall ruleset.

1 ;;; Adguard Home configuration directory
name="adguard_confdir" src="/usb1/adguard/confdir" dst="/opt/adguardhome/conf"So, I'm lost. Why would only TLS servers fail to query in this Mikrotik container?
Can you guys help me diagnose this problem?
