Sorry to anyone who had trouble connecting to our multiplayer server this evening. At the moment, the server is fine but at various points over the last 4 hours, people have been booted out of multiplayer or been unable to connect to the lobby.
We are not yet sure what the cause is but our provider, Fly.io, has reported ongoing issues at their end: https://status.flyio.net/ We haven't pushed new server code this week or had many issues recently so an external cause does seem likely. We will investigate more to be certain though.
99% of our connection issues since launch have been both short enough to not disrupt ongoing games (less than 5 mins downtime) and rare enough to not become a serious problem. This evening was different; it was hard to finish a multiplayer game without a problem occurring, which we know is maddening. We will solve this one way or another, if the problems continue, but hopefully, our provider sorts their issues out and everything returns to normal.
If you experience connection issues, you should reboot the app and try logging in again. Failing that, please post in our Discord and we'll do what we can. You are welcome to @ Jeremy, one of the developers, for a quick reply (if he is awake).
