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.
