DNS over TLS (DoT)

Posted February 12, 2020 919 views

Hello, I’m running an Ubuntu 19.10 droplet. Running Unbound for DNS. I’m unable to turn on DNS over TLS on my nameserver. Each time I try to turn it on, I get a SERVFAIL response! Do the droplets support DoT? I noticed that a reverse DNS lookup on my droplets IP address does not return a PTR, and results in a NXDOMAIN. Would this have anything to do with it? Thanks!
