my xbox 360 is not signing in to xbox live, it disconnects from xbox live immediately

Red Dead Redemption is for Xbox 360, and I have an Xbox One. Whenever I try to play, I get immediately disconnected from Xbox Live.

Ok so when you load up the 360 emulator on the one it immediately says that it is disconnected from xbox live.

When you pull up the 360 guide does it give you a choice to sign into an account at the bottom by hitting I believe the Y button if so try going that route with it.

It appears that when disconnected from Xbox live I still am connected to the internet on the Xbox. Why??? I was updating avatar and while making changes Xbox disconnected me from Xbox live but I was still able to change avatar and save it. After saving it
signed me back into my Xbox live account.

WTF!

I'm definitely leaning at an issue on Microsoft's end either server related or a recent update to the Xbox 360 itself.

360 is plugged directly into the Ubee. I removed it from the internal network.

Ubee is not in Bridge mode. Charter said there are no firewall rules enabled on it. They (firewall) are my responsibility to erect between my network(s) and the Ubee.

What's weird to me, and was reaffirmed after a bit of testing. I'll get the "Disconnected from Xbox Live" message and sometimes won't get the "[username] signed out of Xbox Live". Conversely, if I physically interrupt the connection (unplug ethernet cable)
I always get the "[username] signed out of Xbox Live" message instead of the disconnected one.

In fact, sometimes when I'm "Disconnected from Xbox Live" it doesn't even sign out my username or show on the popup menu or dashboard that I need to sign in to live. I can still access my friends lists and such. It's almost like I'm getting disconnected
from the game server part of live. If I'm in a party or private chat that doesn't get disbanded or ended when I get the disconnected message.

I used to have this problem a few months ago but I couldn't sign back in immediately to live. This started happening when I changed my password a few days ago. Don't know if that'll help. I also get disconnected from Xbox live party's. Its so annoying.
