Why is it not a draw ?

Hi, is it a bug or something I don't know but I ended up losing that game. Any help ? Thanks

It is possible to mate with just a king and knight when you still have material. Imagine if your king was trapped in a corner for example.

Hey so you can put the king in a position such that it is checkmated with just the knight hence it is a loss for white as you ran out of time

Ohhhh thank you both of you I understand now :)
