No Air Drops on my server

I have a new server, hosted by HFB. I have put airdrop.min_players “10” in console and it updates the minimum number of players, but even with enough players on for hours and hours, no air drops. I went to HFB’s website and added it to my config file and restarted the server this morning. Still no air drops. What am I missing?
