I tried logging onto Xbox Live on my Xbox 360 last night, and the error code in the title popped up. I tried many things, such as testing a game through the Xbox One's 360 back-compat, clearing my caches out on my 360, and even deleting my profile and redownloading, but I keep popping the error. However, it still works fine for Xbox One games and my Game Pass catalog on PC. Anybody got any suggestions on how I could fix this?
