So me and my friends were playing on my Minehut server, and our time limit ran out sadly. So I decided to buy a standard package for us to play more! After I bought it I waited for 10 minutes for it to start, but to no avail. So I tried to force-hibernate it or hard reset it, but all it said was "An unknown error has occurred" or "No service found" So I tried loading a backup, but it said that the backup was invalid. So I tried to put a plugin in to get the world file to save it because me and my friend spent a long time building there. All it said was service not found or "Not enough space on disk" Does anyone know how to fix this problem? I quite literally can't do ANYTHING on the dashboard.
