Cant multiplayer
So on my xbox I was in the lobby with one of my friends about to play duos on fortnite and then my controller disconnected but it reconnected quickly so i kept playing but then a minute later it disconnected again and i tried syncing it but it didnt connect so then after 20 seconds the game just closes and it says check your internet my internet is fine after i tested it and when i play solos it works fine i thought it was my nat because it was not open but when i fixed the problem persists this didnt happen before it may be because i hadnt played on my xbox one for around 3 months. Please help
