KNOWN ISSUE: lost_connection / Error Code: 2003

After an almost perfectly smooth gaming evening we experienced a curious disconnection.
It happened during gameplay after a lot of lag (being teleported around the same room and enemies skating).
We soon after both disconnected simultaneously but my error was 2001 and my gf’s was 2003 instead. I think it could be interesting to understand why this difference.
See hour 20:46.
