Getting Signed-Out From Xbox Live Whenever I Launch A Live Service or Game

So a little while ago I got a new Xbox 360 (it's used), and it worked perfectly. That is, until maybe a month or so ago when it began signing me out of Xbox Live whenever I tried to do something. I just carried on as normal for a while, because it was't
really affecting my gameplay, but now it's just annoying. I can't even edit my avatar from my 360, instead having to do it from Xbox Smartglass 360. Which was fine, but I want to be able to launch games and apps without getting signed out. Please help!

:)

 

XBox Live signs me out when I launch my game.

I have 2 downloaded games on my xbox360. Whenever I launch the game, I am automatically signed out of Xbox Live. Then I am told that I only have 10 minutes to play the game. My original Xbox 360 was stolen this past May. Just purchased a used system from
Game Stop. Not sure if that could be the issue or not.

 

Constant sign outs from Xbox Live

I am constantly signed out of Xbox Live whenever staring or ending any app or game. This has been occurring since late November approximately the time of X1 launch. Any ideas why this may be occurring? Mainly play games or use YouTube and Netflix.

 

Hi there, so are you being signed-out whenever you start a game or app? If so, what normally clears this up is deleting the profile from the console (profile only), clear the system cache, restart the console and re-download the profile. Hopefully shouldn't
get signed-out after that.

Delete and re-download profile:
support.xbox.com/.../profile-move-delete

Clear system cache:
support.xbox.com/.../clear-system-cache

 

Me too, I am led to believe it is on their end because the screen does something weird, the app icon gets large and the sign-in blip gets small.

 

My issue fixed. Last night there was some security update. Somehow my profile got deleted from my local HD. I re-downloaded it and so far all is well.
