PC When browsing for servers, servers load up, but cannot join any games

[Spambrah]

HI KF Team,

I can browse for servers, but when I try to join a server, the game doesn't do anything. I can click on other servers, and try to join other servers, but the "Join Server" or "Spectate" buttons don't do anything. If I hit the "Refresh" button, all the listed servers disappear, and no servers show up to join. After about 40 seconds to 2 minutes, an error message pops up saying "Cannot join host".
The same thing happens if I search for servers, but chose to not join any, the error message "cannot connect to host" pops up.
Also, if I browse for servers, then refresh the list, all the servers disappear, and the "cannot connect to host" error message pops up.

At first, I thought it was my internet connection, but other games work fine, as does hosting a local LAN (yes, I know local LAN isn't a WLAN, but the game itself it able to connect multiple people together is what I am getting at there).

Any suggestions that I can do?

This was also happening pre-update with the Gorefiend update btw (not sure if this helps).

Have you attempted to verify game files? This can be done by right clicking on the game from your Steam library and going to Properties > Local Files > Verify Integrity of Game Files. This process will scan through your game content to see if anything is missing or possibly corrupted, and then replace any offending files.

Hey Bad@Chaos. So, I hadn't played killing floor since your suggestion.
Unfortunately verifying the game files did not work.
Do you have any other suggestions for me?
