Can't log in constantly giving me problems

Yeah, Im having this problem. I can only log onto my account on the dashboard but if I try playing a game or use an application It logs me out and gives me this error message "Sorry, this profile can't connect to xbox live on this console. To fix it, downlod
it again."

Like he says, check if you are still logged in or logged into the correct account. My minecraft on IPhone always logged me out constantly.

Can't log in to my second xbox. Keeps giving me the 80151103 error code.

X-Box One - Can't log in, rebooted the router many times and no help. Rebooted the X-Box many times and no help. Even when the X-Box is sitting next to the router it will drop out. Computer's are fine, log in and no drop out at all, even the computer that
has a wireless connection and is in a far bedroom. The X-Box is constantly dropping out and always a problem with log in. Carrier is Spectrum, no problems there. Out of two Windows Ten computers, a Samsung Smart TV there has never been issues, but X-Box is
a constant problem.

I can't log in to the Ubisoft servers I get some stupid message sayin "The Ubisoft servers are not available... blah blah blah."

My NAT is open and do not have any online issues whatsoever, it is only AC: BF that gives me this problem. I can't find any solutions, this sucks cuz I can't play multiplayer.
