When looking at the servers on this game, you can see a large number of them with 0 players in them. I think this may be related with the fact that the game was recently dislike botted from 72% to 37%.
This bug started happening within the last couple of hours. There are also quite a few servers with only 1 or 2 players which is causing a lot of new players to leave the game as the server they are in is empty.
Edit: I shutdown all servers to prevent users from joining empty games then leaving.
Edit: After shutting down all the servers the problem still persists.
Edit: The problem has stopped occurring after a few hours.
