Can't play arena

When i want to go to the arena i have an error message who said i can’t connect to the server, my nat is open and my connection is good i can play to the other game with any problem, i have already reinstalled the game. This is the third day i can’t play and that make me crazy (sorry for bad english)

Where are you from if I may ask?
Start out by hard restting your xbox and power cycling your internet
If neither of those things fix the issue, it may either be Your ISP or your location
I’ve read several posts on waypoint talking about how players form south America especially were having problems connecting to H5 servers
