So after trying to fix this for days I finally managed to do this. After restarting my computer I noticed resilio sync would always restart in the rslsync user, even though I followed all the steps on the setup page.
The setup page for linux is about half of what you need to do but here is the rest...
After installing, do step 1
step 2
go to the config file at "~/.config/resilio-sync" and change listen x.x.x.x to "listen" : "0.0.0.0:8888".
step 3
save and restart linux
hopefully that will help you like it did with me
