DNS over TLS (DoT)

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!
