What is ‘Exception in Server Tick Loop’? 🛠️

This error can occur on any Minecraft server, whether Forge, Fabric, Spigot, Paper, etc. Basically, it appears when your server “crashes” due to a problem in the tick loop. 😱


Common Causes

The main cause is usually corrupted .json files 🟡. These files configure bans, admins, whitelists, etc. Manually altering them can cause them to become invalid. ⚠️


Example of a Common Issue❗:

Common Problem ⚠️: Editing .json files directly.

Solution ✔️: Use in-game commands like /op instead of manually editing the files.


Step-by-Step Solution

  • Access your HolyHosting panel 🖥️.

  • Log in with your credentials 📜.

  • Locate the files: banned-ips.json, banned-players.json, ops.json, usercache.json, whitelist.json.

  • Delete them and restart the server.

Trying to join the server after this should resolve the issue. If it persists, there’s likely another cause, and we recommend contacting our 24/7 support 🕵️‍♂️.


Server Optimization 📈

You can prevent these errors by optimizing your server. Check our guides and make sure not to edit .json files manually.
