How is this a loss on time?! Chess.com server?!?!

Played a really weird back and forth game today that was poorly played by both players due to the complexity of the position. But how I lost is ridiculously unfair.

here’s a screenshot I took the moment it happened, because I was upset I’d lost with my opponent having 0.00.1 on the clock, but then I noticed something….

chess.com clearly registered that id moved on time, as the “loss on time” icon is over the square I moved my king to! Surely if the site has registered the move I can’t have timed out before I played it?

can someone on the technical team comment on this? I don’t think I deserved to lose those rating points, and would quite like them back, please! 

@martin_stahl I’ve raised a support query, anyone else who can help?

The client can register a move but I it's possible the server doesn't receive it in time., after allowed lag is compensated for

It would appear the code has a minor bug in that case, where the glyph loads in the incorrect place.

I had 0.06 on the clock the previous move so it’s not like it’s a premove bug… human reaction speeds are normally faster that 0.06s so it’s a little frustrating….

What kind of reaction is that?

An annoyed reaction

I reported the glyph bug and staff looked into it. It appears you likely were disconnected; the sever never received your move

Are these glyphs processed at the client side?

Thanks Martin, but with such fine margins at the end of this game time-wise it seems patently unfair that my opponent was able to get the win when I clearly made my move (even if the server didn’t process it fast enough)…

The server is the official arbiter of what happened.

Its not that the move didn't reach the server in time, but server never received it. However, if the server didn't receive your move on time, and the time ran out, on the server, then it's a loss if your opponent has sufficient material to mate.

Its many bugs on this site. Me for example, "lost" many games this day because of opponents abandon the game...

The system says it was you losing connection, not your opponents.

Did something change in your setup?

I dont know, i mean, i know the statistics. Most of those "games" were abandoned by others and then counted as "wins" by the site.

It can be the arbiter all it once, an arbiter should still take into account demonstrable evidence, such as a screenshot that shows that the move was made. I still don’t understand how the server didn’t register it if it knew to put the “you lose” icon on the square I moved to? Surely that comes from the server?

You're connection to the server was lost if the server ended the game as a loss for you.

Eh? Then wouldn’t it show as a disconnect? Not a timeout?

The screenshot, where the glyph shows on the square where you had moved the king, is on the client. The client does not keep the official clocks,, so it's possible to have a move successfully made on the board, with time in the clock, but for you to run out of time on the official server clock.

The server does not put the glyphs on the board, the client does that. That's the bug.

The server never received your move. Had it been received, but not in enough time, biased on the official clock and calculated lag compensation, staff would have seen that.
