So for anyone having this problem, I found the solution. Restart your router.

Hi all, yesterday I tried to play Chiv, but I found no servers there, logically I ran through all the topic on steam, but that wasn’t effective, deleting folders and configs did not help. I also tried to reinstal the game, nothing… I also tried to click community tab in main menu, but the game crashed, and now it’s crashing all the time… I’m kind of sad, because I love the game, I worked on my skills and now I’m unable to play it anymore.
