Can't play Halo 5:Guardians

Hello, I need your help. Since yesterday it won’t let me play online. On the screen it only says “Retrieving data” and it doesn’t do anything, also all the stuff I got in the packages is gone, and I’m back to level 1. It lets me play campaign, but if I go to arena it sits there like that with the line “Retrieving data.” Please, I need your help.

Hard reset your Xbox always works for me also reset your router if that doesn’t work
