For the past 2 weeks I keep encountering issues loading games or outright freezing mid game. Internet is fine, I’ve done all the crap from resetting to redownloading the game. It’s like I find a match and it loads 90% and then says an error occured. I’ve lost hella rank because of this since the system says I quit the game. I could explain more but honestly what gives!
Are you playing on Steam on Windows store?
Do campaigns work fine?
Can you try playing custom games on a bunch of maps and see if they load up OK locally? (I am assuming there are LAN games on the PC version of MCC)
Nope, Xbox one. If my ethernet is out the only thing I can do is the campaign. The actual game itself can take 30 minutesnto load. I’ve gotten kicked out of 3 games today. Either the game froze in the actual game, I got stuck im the pregame loading screen, or literally the games would just not load. Internet is fine. I think -Yoink- is getting overloaded because of everyone playing but this is ridiculous man. Literally I went months with no probs and now all week it’s the same -Yoink-.
And I’m talking about matchmaking in slayer. And literally right now I’m counting 20minutes I’ve been waiting for Halo 5 to load. And as said before I’ve done allll trouble shoot -Yoink-. I think Xbox live needs to get their -Yoink- together and beef up their infrastructure. Who knows maybe I need a new Xbox but dude like literally the ONLY game I play is H5.
And apologies I love all you do 343 but I’m just annoyed. It’s hard to get better when you can only play 3 games a damn hour 
Well after waiting for 45min to load the game I’m going to restart my Xbox for the 2nd time today.
