Im having trouble connecting

Every time i start loading up Halo 4, there’s pop up that tells me that Halo 4 has an update that needs to download even tho it doesn’t tell me what update exactly. Problem is that every time i press Download it fails and disconnects me from XBL instantly.

Anyone else having this problem?

I tried resetting my modem and everything. My internet is fine and I’ve never this problem before with any game.
