Miért nem lehet felcsatlakozni a minecraft szerveremre? (a többi lent)

Az Infinity hostingtól bérlem! Ma rendeltem meg és nem bírok felcsatlakozni rá, mert ezt adja ki: A belépés sikertelen: Érvénytelen munkamenet (próbáld újraindítani a játékot) Pedig sokszor újraindítottam! A konzolban pedig ezt írja ki: [Multicraft] Received start command [Multicraft] Loading server properties [Multicraft] Starting server!
