strange disconnexion in middle of the game

I have a good internet connexion but somehow I get disconnected from time to time from lichess and lose on time and there is no way to reconnected once it happens. Seems kind of strange since it always happens when I am low on time and completely winning. Is there some kind of bug that some users are abusing.

I have a feeling it is just bad internet... I've gotten that a lot recently too, very frustrating. Like my ping right now is ~2000 :(

I believe there is an exploit to disconnect your opponent.

@Melora - there is a simple test for that. Try Malwarebytes Anti-Exploit (free) and see if the problem persists - I have it, and still get this occasionally (no difference for me).
