Side note, but do you know if the -host-name and -tls-host-verify options actually add anything to the default config ?

I have only server-tls 9.9.9.9:853 and I get the same authentication output at https://dnscheck.tools/ both with and without the two options.

Check the contents of /tmp/smartdns.conf

The only difference is that the two options are included in the conf file only if they are explicitly listed in the Additional Options section of the GUI. However, DNS authentication at https://dnscheck.tools/ still appears OK even without them, so its not clear to me whether the options actually do anything.

Thanks everyone for trying to help. It looks like the problem is really on my side. I also noticed this in the log
un 26 01:41:02.404 gate user.warn smartdns: http server query from 9.9.9.9:443 failed, server return http code : 502, Bad Gateway
