First: create a server from the in game menu
Join and play for a few minutes
Exit
Now go back to your BRINK browser. Servers should be there now.
Its a recent STEAM issue for many games.
If that didn’t work then:
Can you see servers listed in the STEAM server browser with the BRINK filter?
If so, then you may need to forward ports or allow steam.exe and brink.exe through firewall in order to see them in the BRINK browser
Make sure that your BRINK browser filter settings aren’t blocking
When you updated your dedicated server files, it installs the DLC maps
You need to add the new maps to your map rotation / map vote cvar line
//////////////////////////////////////// /////////
//ONLY ENABLE ONE MAP ROTATION - FIXED OR VOTE!//
//////////////////////////////////////// /////////
//Maprotation - FIXED!
//The server will run the below maps in the order listed.
g_mapRotationFixed “mp/aquarium,mp/ccity,mp/reactor,mp/refuel,mp/resort,mp/sectow,mp/shipyard,mp/terminal,mp/lab,mp/founders”
//Maprotation - VOTE!
//Server will allow the players to vote which map to play at the end of each round! They can ONLY choose from the maps listed below!
//g_mapRotationVote “mp/aquarium,mp/ccity,mp/reactor,mp/refuel,mp/resort,mp/sectow,mp/shipyard, mp/terminal.mp/lab,mp/founders”
Players who don’t have the new maps will be disconnected from the server on map change
