unable to connect on online modes.

for about 4 days now when I start up halo 5:guardians. I get an error saying “we are unable to get your latest saved data” "try again or use offline.
I select use offline and a message comes up saying "error authorizing user with halo 5:guardians services. you will be unable to access online modes.
when I try and select an online game node I get an error saying “unable to connect to the halo 5:guardians lobby service”.
anyone else having this issue and know whats going on or how to fix it?
there is nothing wrong with my internet connection. I did the network testing and they all say working my NAT is open says all services are available.
I have been searching forums all weekend and cant find anything relevant and recent.
