Can't connect my 360's profile when i play retro games on xbox one

The games are all digitally owned in my library. There are no discs. I had no troubles with this on my original Xbox One that recently broke and required me to buy a new Xbox One S. The emulator I am referring to is the internal emulator that all Xbox
Ones run when playing a 360 Backwards Compatible game. When I install a 360 game and try to run it on my Xbox One S, the game will load HOWEVER I cannot connect to Xbox Live while in the 360 emulator. Due to a recent troubleshooting that suggests uninstalling
the game and clearing 360 cache and profiles, I would need to redownload my xbox live profile for the 360 emulator ON the One S. Since the emulator WON'T connect to Xbox Live, despite my Xbox One S BEING connected to Xbox Live, I cannot download my profile
and therefore cannot play and save my progress. I've tried with multiple games but they all give me the same issue of being "unable to connect to xbox live". I've tried all of the Mass Effect games, the Dragon Age games, Star Wars: The Force Unleashed games,
Banjo-Kazooie, and Fable series of games and NONE of these will allow me to connect to xbox live.

Same problem when connected via Ethernet cable. Downloaded my profile to one of my kids 360's just fine and other content downloaded fine as well. I move my profile to my console and I can't connect again.

I can't, it says that it's not connected to the internet. My xbox one is connected to the internet but when I try to play a 360 game on the xbox one it says that it can't connect to the internet.

The problem is not resolve totally.

Because if you restart to use Ethernet connection on your xboxone, the bug come back and you will not able to connect your 360 profile to internet. You can play only offline with retro compatibily.

The 360 console emulate on your Xbox one(and all his games) work online only with a wifi connection. If you use an Ethernet cable is not possible go online.

My 360 (my real 360) use an Ethernet cable to go online, because have not wifi on my console version. But All work good. So The problem is not my profile, is a bug on The Xbox one.

I am just now having this issue for the first time. A couple weeks ago I was able to play Halo Reach on my Xbox One but today, when I load it up, it won't connect to Xbox live. My Xbox One is on a wired connection - open NAT and all services good - however
the "360" won't connect. I tried correctly hard restarting the console twice, clearing the 360 saved data, and playing other games but all have the same issue. The "360" cannot connect to Live. I also tried deleting my 360 profile like suggested in a number
of forums but when I go to sign in and download the profile, it can't connect anyway in order to download the profile.
