Well, after a small update by Steam today, I and probably couple of players cant join the server
It shows that the server is at the limitation 64/64 and when you try to log in it will say that "Your Connection to the Host has been lost." Even when you type the IP address of server on console it still says " Authentication Failed"
The method to log in the server until now tested by me is:
1) go to my documents > my games > Chivalry folder > UDKGame and delete the config folder
2) Exit steam (restart steam) and verify cache.
iF AFTER THIS YOU CANT FIND THE SERVER GO TO STEP 3
3) open console and type "open 31.186.251.152:6000"
(to log in server directly, after this you can see the server normally)
P/s: Now I can log in but the server has little players, only about 20. So hope everyone find this help to join the fight ^^
