Syncing local server with seedbox

I torrent to a seedbox, and said seedbox has great access tools and you can install plenty of useful applications like Resilio Sync, Syncthing, etc.

My local server is running Fedora Server OS. I'd like to get an automated 1-way sync up and running, but I'm having a lot of trouble. I was using Syncthing in the past, but it's really not meant for one way syncs and caused some issues. I've been trying to set up Resilio Sync, but on Linux I cannot figure out how to get access to the web UI. Resilio's own documentation is frustratingly obtuse - it's great for setting up the service under systemd but then basically has nothing about how to actually get webui access from another machine on the local network, excrot for a reference to a command that doesn't actually exist.

If anyone either 1) knows how to set up Resilio Sync on a Linux machine such that I can hit the web UI from another machine on my local network or 2) had a better way to set up 1-way sync between my seedbox and my local server, I would love to learn!
