As Boppins mentioned, we've reached out to the developers to bring this to their attention. They let us know that "Unfortunately for the Armor Games player, [our] platform cannot be returned into service for a few weeks due to technical difficulties."
I'll keep you updated as I learn any new information.
We've been doing some testing on our end and the game looks to be back to connect to the servers. I'll keep this stickied for another week in case someone else reports problems, otherwise, this one looks solved!
