Client requested disconnect

I’m sure you’ve seen others complain about this issue before, it now plagues me. About 2-3 minutes after logging in I get disconnected. I can’t even get into a game. I’ve searched a few forums, but no one at blizzard is really saying anything to help? Please someone tell me why I can’t play on my Xbox. Why does my PC let me play but my Xbox won’t? How can I fix this
