Yea, it works for me, but there were no great guides. If nothing is in the DB, try checking HTTP error codes, or setting the RUST_LOG to trace (which gives you a log line for every item synced).

A problem I had that seemed like nothing was saving was the nginx proxy wasn’t doing things right, and I couldn’t tell. Using the local IP worked, and after making some nginx config tweaks I got it working.

I ended up making suggestions here based on my experience: github.com/porelli/firefox-sync

I didn’t exactly use that repo, but started with it. Their nginx config works, though.
