Why does this happen every time I play a game. You have 10 minutes before being signed out...

I'm having the same exact issue but mine started last night. I'm playing a game and suddenly I get signed out. So I tried playing a game that does not require being connected to the internet and I still get signed out. I then tried signing in and just
sitting at the dashboard menu, 10 minutes later I get signed out. All my other devices in the house can connect and stay connected. I even tried my ps3 and it stays connected to the internet as well. I have cable internet and connected via ethernet and
tried resetting the modem and xbox multiple times. Never had any problem till last night. I get signed out 10-15 minutes after I sign in.

I'm getting this error message CONSTANTLY now -- it's taken me as long as 10 minutes to get into a game. It never happened to me before this most recent patch & it's starting to annoy the hell out of me.

I don't know what it is with cod devs, but every time they patch their game, it gets harder to play.

I tried this but it keeps signing me out. Does my xbox one S have a problem with it? Should have stated this before but it signs me out when i play minecraft locally with my brother within like 10 minutes of playing, within like an hour or so when i play
minecraft by myself, within 2-3 hours of playing rocket league and other games. Like i said it still keeps signing me out, even after the reset you suggested.

That happens to me occasionally, just XBL being laggy.

Does it happen every time you sign in?

Also, how is your internet connection with a computer?

This seems to be a common issue. I would try to restart my network by un-plugging your router and modem for thirty seconds and then plugging everything back in. If that doesn't work try to clear the system cache. To do this go to system settings--->memory--->
then highlight your hard drive that contains you account---> then press Y on your controller---> then click clear system cache.
