If you have no servers appearing in your Server Browser, try the following;
1 - Restart Steam
Chivalry uses Steam to find servers for the game. The most common cause for the server browser not populating is an intermittent connection to Steam.
2 - Default your Server Browser Settings
Ensure that your Server Filter is set for <All> and no other boxes are checked.
3 - Allow Chivalry to access the internet
Windows Defender, firewall applications, or anti-virus programs sometimes block required internet traffic from our game to Steam. Ensure that Chivalry is given full permissions through your firewalls and anti-virus programs (this is called “white-listing”).
4 - Change Server Filters and Revert Filters
Sometimes a filter setting can get stuck.
Open the Server Browser
Set your Perspective to First or Third
Set your Perspective back to All
Save and Refresh the server browser
5 - Ensure that you are Opted out of any Betas
Right click on Chivalry in your Steam Library List
Select Properties > Betas4) Select None from the dropdownbox
Betas are often older or archived versions of the game and do not typically have any servers running.
6 - Reduce your In-Game Browser Pings setting
If your browser pings the Steam server list too fast or frequently, servers may not load. Reduce the setting to 1500 or 3000.
Go to Steam > Settings
Reduce In-Game Server Browser value to 3000 or 1500.
7 - Run in 32-bit mode
If you have an older computer that has been upgraded to a 64bit system, running in 32bit mode may allow you to see servers in the list.
Right-click on Chivalry in your Steam Library
Select Chivalry: Medieval Warfare (32-bit) or Chivalry: Deadliest Warrior (32-bit)
8 - Set your router to use Port Forwarding
