Transferred my singleplayer world onto a multiplayer server hoster and lost my inventory
I wanted to host a multiplayer vanilla survival server on Aternos for a Discord I frequent. After opening the server, not only is my skin gone, but my inventory is, too! I'm not sure what happened here, so can someone help?
This sounds like Offline mode
To correct this, find "Online-mode" in server.properties and change it to true.
online-mode=true
Your inventory disappears due to how minecraft servers handle UUID's when not online.
