Out of sync

I played two matches and both kicked me out. It said I was out of sync. What does that mean? I went down an entire rank and screwed 2 other people thanks to this huge error. What happened?

It means you lost connection to the match or they did. I know sometimes it’s the game/server’s fault and not your own.

I just got disconnected from a winning game. Is 343 going to fix this? Is the 4 time this week.

I got disconnected from two stronghold games in a row, it hasn’t happened in blitz though. My gamertag is tankslap and I play on an Xbox one.
