I spawn in the void / free-fall and get kicked when joining — how do I fix it?

Joining your server and immediately free-falling through the void before getting kicked is a frustrating bug, but it's usually fixable. It almost always means the spawn chunk isn't loading — either your world data is in the wrong place or the server is too laggy to load your chunk in time.

Why this happens

When you connect, the server needs to load the chunk around spawn and place you on solid ground. If the world data can't be found, or the world folder structure is wrong, the server drops you into empty space. Severe lag on join can cause the same symptom.

How to fix it

1. Check your world structure. If you uploaded a world, confirm level.dat sits at the root of the world folder in the Files tab. A wrong structure makes the server drop you into an empty void.
2. Set a safe spawn. Run /setworldspawn from the Console, or teleport yourself upward to solid ground.
3. Address lag on join. If the server simply can't load your chunk in time, improve performance or add RAM (adjust Xmx in the Startup tab).
4. Restore a backup if the world itself got corrupted — re-upload a known-good copy of your world folder via Files/SFTP.

Warning: Restoring overwrites your current world. If you might want the present state, download a copy first via Files or SFTP.

Frequently asked questions

I uploaded a world from single-player and now I fall into the void. Why? Single-player saves nest the world one folder deeper. Make sure level.dat is directly inside world, not inside a subfolder.

It only happens for some players. Is that still spawn chunk loading? That pattern usually points to lag loading their chunk. Improve TPS and consider more RAM.
