Game always disconnecting every time I finish playing the Gaunlet

Hi, the game keeps on disconnecting every time I play the gauntlet and I was almost done with the objectives so why is this happening to me when everything was just fine in Saturday. I have been robbed of 7 matches with like 4 wins, all of which I was disconnected and my game didn’t register. I have attacked a video to clarify this . Help me out please .
