Step-by-Step Fixes for 500 Minecraft Error Server Shutdowns

✅ Ready to fix it? Follow these proven steps in order. Most users resolve it in under 30 minutes.

1️⃣ Check and Boost Server Logs

First, open your latest.log or crash-reports folder. Search for "500" or "Exception."

• Copy-paste errors into Pastebin for analysis.
• Pro tip: Use mclo.gs for instant sharing.

2️⃣ Allocate More RAM (The #1 Fix!)

Default servers choke on 1-2GB. For 10+ players:

java -Xmx4G -Xms4G -jar server.jar nogui

Upgrade your host (Aternos, Apex) or VPS to 4-8GB. Boom—shutdowns gone! 🚀

3️⃣ Update Plugins and Server Jar

Download latest PaperMC (optimized for 1.21) from papermc.io.

1. Backup world.
2. Delete old plugins; reinstall compatible ones (e.g., EssentialsX 2.20+).
3. Test with vanilla first—no mods.

4️⃣ Repair World Corruption

If chunks are busted:

• Use /fill ~ ~ ~ ~ ~ ~ air on suspect areas (backup first!).
• Run MCA Selector tool for chunk trimming.

5️⃣ Firewall and Port Check

Ensure port 25565 is open. Test with telnet yourserverip 25565.
