It is not always the fault of your connection or the browser.
When your opponents time runs out, but you lost anyways,
it can be because the moderator stopped the tournament to
help your opponent win.
So you never get the move your opponent played, and will
eventually be given the loss for leaving the page as you are
stuck there.
Evidence of the moderator's cheating will be that the
tournament is not reloaded into the tournaments display
page because the moderator stopped the tournament
before its natural time ran out. The web page makes the
assumption that it was deleted.
So next time, just take screenshots of all the mayhem
and send them to Lichess. You'll find that they don't care
about your explanation, or evidence.
