Hi everyone,
We’ve noticed that players will be experiencing connectivity issues when trying to run the game at the moment (the error message says “Back-end server is at capacity” which probably isn’t accurate as it’s a quiet Monday morning).
The devs are working on the issue right now and will hopefully resolve it quickly. I’ll update you as soon as I know more details. Your patience is appreciated in the meantime 
Update: this should now have been fixed and the game servers should be working as normal again.
