Can not access multiplayer

So after a 20 hour download I finally load up halo and in the bottom right corner it says offline. My xbox is connected to the Internet and can run anything else online. I have quit halo, soft reset, hard reset, and reset my router. Any suggestions or ideas would be appreciated

Trying find a solution as well my friend can’t play with me

Did you download the 9gb day one patch?
If so and still a problem try posting this in the tech support forum. Be detailed. Someone from 343 will help you.

I haven’t been offered any more downloads, there were two downloads last night before I went to bed. Woke up with just one.
