Folks, I was trying to enable DNS over TLS via systemd-resolved. I've edited /etc/systemd/resolved.conf as follows: [Resolve] DNS=1.1.1.1 #FallbackDNS= Domains=~. #LLMNR=no #MulticastDNS=no #DNSSEC=no DNSOverTLS=opportunistic #Cache=yes #DNSStubListener=yes while monitoring the network (with tcpdump) to see if the resulting behavior was the intended one, it seems a TLS session is established with the target server, but then the server closes the connection. I got the same results with 1.1.1.1, 8.8.8.8 and others. Any clues? P.S.: systemd-resolved ends up doing parallel resolution with traditional DNS (despite the setting of "Domains" above) -- that was the motivation of my other previous post. But my main question for *this* message is what may be going wrong with the TLS one. Thanks!
