🆘 Help! My server is acting weird

Noticed something strange going on with your Minecraft server? Like:

  • Your world appears reset or is suddenly empty
  • Blocks disappear or don't load properly
  • Plugins or mods aren't working
  • Players experience lag or can't connect
  • Or worse: your server crashes on startup

Don’t panic! This guide walks you through the most common problems and how to fix them.


1️⃣ Did the server actually start?

Log into the OXY.Games Game Panel and check if your server is running.

👉 Open the Console and look for any errors during startup.
Pay attention to red messages like:

  • Could not load plugin: EssentialsX
    Incompatible with server version
  • Exception in server tick loop
    Often caused by corrupted worlds or buggy mods

Seeing something like that? You’re already on the right track. Copy the error and Google it — or send it to our support team.

💡 Coming soon: Our OXY.Games AI Assistant will help explain console errors and suggest solutions automatically. Handy, right?


2️⃣ What changed recently?

Think back:

  • Did you add any new plugins or mods?
  • Did you change settings in server.properties, like level-type or world settings?
  • Did you switch server type (e.g. Paper to Forge)?
  • Was there an automatic update?

Even small changes can break things. Identifying recent changes makes it easier to fix issues.


3️⃣ Try restoring a backup

It’s easy to restore a previous backup from the panel:

  1. Go to the Backups tab
  2. Click Restore on a date just before the issue started
  3. The server will restart with the selected backup

⚠️ Always make a backup of your current data before testing anything!


4️⃣ Server crash? 😱

Crashes can happen at startup or during gameplay. Here are some likely causes:

At startup:

  • Invalid or outdated plugin/mod
  • Corrupted world files
  • Not enough RAM allocated
  • Missing server.jar file
    Console message: Unable to access jarfile server.jar
    ➤ This means your server can't find a startup file. Install the correct Minecraft version or loader (Forge/Fabric).
    👉 See our guide: Change your Minecraft server version

During gameplay:

  • A mod causes instability
  • A player triggers a bug (e.g. command block, TNT)
  • Corrupted chunks

Fix:
👉 Check the console and relate the error to the last added mod or action.
Test temporarily with a fresh world or without mods.


5️⃣ Experiencing lag?

Lag or stutters can be caused by:

  • Too many mobs, hoppers, or redstone machines
  • CPU-intensive plugins
  • Poor internet connection (server or player-side)

Use the Spark plugin to analyze performance.

6️⃣ Clean up temporarily

Want to test if the issue is caused by mods or the world?

  • Move your current world, plugins, or mods folder to a temporary location via File Manager
  • Restart the server and check if it runs fine
  • Re-add folders one at a time

⚠️ Make sure you have a backup first!
