i premove the move but i lost !

lag.
or, you disconnected

It was probably because ping from your network to lichess servers to get the move so if you had like 0.1 seconds you can lose if the ping was more than 0.1 seconds!

Can be glad it happened against a too strong opponent anyway

Between your move d6 and the move Bg5 (he premoved) of your opponent you had 00:00.00 time to make the premove.
That might be too short. Why don't you play during the remaining 8 seconds of your time?
