my laptop disconnected for as i could see it, literally a few seconds, and as soon as i reconnected, i get prompted saying i lost the game by abandonment.
Disregarding how desperate my opponent must be to take cheap wins like that (not a comment i'll apologize for), i must ask how long it should normally take before lichess decides that i've been offline for long enough to warrant losing the game. Especially given that as far as i've seen i've been offline for a few seconds, then losing the game right after i reconnected. In real time i see myself going offline and being told i lost the game in the span of 5 seconds. And this wasn't a blitz or rapid game.
