Still having the same problem here. Connecting is greyed out and constantly saying "connecting to matchmaking service" when I hover over it with my mouse. The work around and re-installing still didn't work. I'm in England.
Hey Azurescens, we're aware of this issue and are hoping to have more information about this by Monday 10/22. The leaderboards are supposed to reset at the end of each month, so it seems they reset early.
@zupeman Hi Zupeman, you should have received a prompt to claim the season pass if you were logged in during those hours. There was an update 10/19/18 around 11 PM PDT if that's what you are referring to. We are still holding a giveaway where you can enter to win one of ten season passes: https://gleam.io/aoGak/zeus-battlegrounds-season-0-pass-giveaway
