I was playing a random game on checkpoint when suddenly the game started to act like if I didn't have internet (I have very fast internet and that kind of problem is impossible)
so I left the game and looked for another... the problem is that now I see a message that says "unable to find game" after 30 seconds waiting in the menu.
