Connection issue during match

General

Playing on Lichess. Something happened which meant board had to reconnect to Lichess. However when the connection returned the game was completely stalled and could not make a move or resign out of it. The game carried on and I lost on time as a result.

Seems like WiFi cut out for an extended period - and perhaps the game concluded while out and our system did not message that correctly.

I will ask the team to review.

This was a very unfortunately timed network hiccup and a separate bug on the board that I’ll fix. Timeline:

  1. After white played rook f3 → f1, the WiFi connection dropped out, dropping the game connection to Lichess. The board immediately starts attempting to reconnect.
  2. With 2.3 seconds remaining, black plays queen E1->H4, the game screen on the board pauses the clocks to show that the move was accepted locally, but we haven’t heard it confirmed from the server yet.
  3. By the time the board reconnects the game has already ended on time.
  4. When the board reconnected, ChessUp2 didn’t understand the game ending it received, and did not display it. I’ll fix this.

I can’t say why the WiFi connection dropped. When it came back, the WiFi channel was different - it’s possible the access point decided it was better to move the network.
