Error In Beta Halo 5

I am having problem when trying to play the Multiplayer Beta Halo 5.

I’ve done everything:

I have Halo MCC
I have Halo Chanel
I have watched Halo: Nightfall
Already deleted the demo and the demo patch 9,5MB.
Already deleted the Halo MCC and his Patch.
Already deleted the Halo Chanel and his Patch.
I’ve done everything in my internet.
I took an XBOX One with a friend and in my work.

I have looked in forums know about the error. And found nothing.

Can anyone help me?
