I’m wondering if anyone else is having issues with the servers today. When I try to load up the Warzone menu is takes awhile to connect lobby and then It tells me that I am unable to match. I back out of that then I am unable to select anything and I am forced to exit the game.
I too cannot search for a game, Warzone or Arena
EDIT: United Kingdom. Either get “Xbox Live Party Service” error, “Matchmaking” error or “Can’t find other players error”.
EDIT 2: Can’t even look at Carnage Report…
Exact same thing for me (i am in France).
Xbox live status is OK.
It seems that this is a global issue: http://downdetector.com/status/halo
Same. (Connecticut, USA)
Getting an error myself whenever I try to make a lobby.
“Attention
There was a problem with the Xbox Live Party Service.
Please try again.”
Same issues 
on one of my few days off whyyyyyyyyyyyyy
Same here getting “ATTENTION, There was a problem with the Xbox Live Party Service., Please try again”
Those are the same exact error messages I’m getting.
Now it is back for me, but it seems it is not finding other players.
I still can’t play.
I am also having multiplayer issues. From error to can’t find a game, etc. KY USA
Is it xbl or just halo? because I’m having issues getting into a party as well?

Same problem here.
Getting this error when first trying to start a custom game, then trying again leads to the custom games menu stalling out.
Same here, was just playing team arena got my a rank, then it booted me off the lobby.z
I can’t do anything. It’s not just multiplayer, I just simply cannot start a game without some type of error message that sometimes doesn’t make sense. For instance, I’d be loading a campaign mission and it would say can’t find players. It would be nice if 343 at least acknowledged the issue.
Same here.
“There was a problem with the Xbox live party services” and “Unable to match”. : /
Same. At least acknowledge it 343!
Unable to match error. Why today ): (North America) I guess I’ll just try to watch those videos for req packs
Before you all jump to the conclusion that this is an issue caused by the Halo servers and 343, be sure to check the status of the Xbox Live services. In the US the link is here:
https://support.xbox.com/en-US/xbox-live-status
There is currently an issue with matchmaking across the board with Xbox Live. It is not isolated to Halo 5.

Same problem here. I finished a warzone game and then I couldn’t play anymore. Got an error message saying “there is a problem with xbox live party service”. I tried going in the warzone lobby again but sometimes it doesn’t let me select warzone nor warzone assault. When I can select warzone to play it says it can’t match players or something like that. I just want to play, this is so frustrating. I’m in Santo Domingo, Dominican Republic btw.
