Unable to connect to the Halo 5: Guardians Lobby

Help. I have two Xbox’s that I play on. I always close out of one Xbox completely, (home button, quit game), then home button again and shut off console. But now I can’t log in or play on my second Xbox.

It’s just connecting to lobby then says its unable to.

Oh awesome. As soon as I hit submit for this post, it lets me play. Apologies for pointless post. X2…
