[CS:GO] Server Not Showing Up In List

[dv9unknown]

My CSGO server seems to not show up on the server list.
The API returns true:
http://api.steampowered.com/ISteamApps/GetServersAtAddress/v0001?addr=162.220.242.83:27015&format=json

sv_region is set to 0. I tried setting it to -1 and 255, both had no effect.
