The software is stuck and cannot close positions in time, resulting in liquidation.

On the morning of December 4th, gold surged, and the platform suddenly froze. As a result, the position could not be closed in time, so that the account was liquidated. If the platform was not stuck, I could have closed the position. Who would bear the loss? Other positions in the account also exploded. A few days later, when I logged in to mt4 and the backend, I found that I could no longer log in and my account was deleted. What does this mean? Request compensation for the amount of liquidated position.
