Telemetry for the HTTP side is in my ToDo list yes, since I'm using a 3rd party library for the webserver I still need to figure out how to do it right. For HTTPS to work you need to provide a valid certificate path in :https_keyfile but right now I would recommend sticking Caddy or Nginx in front of the tracker if you want HTTPS. I have certbot integration planned but is not a priority since most of the torrent peers use UDP.
