It hapened a few hours ago. But im normamaly signed in, but for some reason it signed me out and i couldnt get back. Worst of all i couldnt tell anyone about it :(. I signed in to xbox.com and everything was ok there.
Didn’t happen for me.
It’s known problem were if you click sign in, it will load and just not sign you in, there is no fix for it, even switching browsers or computers or even trying on a tablet/smart phone doesn’t work, you just have to wait it out, it can last for 10 minutes for up to 2 hours.
I don’t know if there is any planned fix or solution but I know the dev team are aware of it.
A recurring problem for me is that whenever I access this site via the address bar, then try to sign in, Google Chrome will tell me that this isn’t Waypoint.
However, if I use Google to find Halo WAypoint, then sign in, things will work.
Have you not been able to sign in before, OP?
