Empty server browser
I too have problems getting servers listed in the server browser. Problem only started today, yesterday it worked fine.
Please remove the line “Suppress=DevOnline” from your UDKEngine.ini located in Documents\My Games\Chivalry Medieval Warfare\UDKGame\Config. Then open up the game and sit in the server browser for about 10 minutes (grab a cup of coffee) or until you see servers show up, try joining one (preferably an Official Server). If you try to join one, but it doesn’t let you connect, please exit the game normally. If no servers show up, please exit the game normally. Then after either scenario, attach the Launch.log found here Documents\My Games\Chivalry Medieval Warfare\UDKGame\Logs in a reply here.
Doesn’t look like you removed the line “Suppress=DevOnline” from the UDKEngine.ini.
Did you try changing your gamespeed in the server filters to anything but 100% and then back to 100%?
