How to Fix Exception in Server Tick Loop Error in Minecraft

The exception in the server tick loop error will prevent your server from loading and deny you access to your game. The good news is that the following error is not one without a solution. Read on from our programmers on how to solve this issue.

Method #1: Review Server Files

The first step is to review your server files to ensure none of them is missing, especially the JSON document.

You can do this by using the web-based FTP client which allows you to manage your Minecraft server docs. Navigate to FTP file access and log in using your dedicated panel password to review your docs. Once it accepts, they will redirect you to the home directory of your server. 

Step #1: Stop the Server

To bring your server to a halt, you can use the /stop command. This will end your server activities and save all the data. This includes worlds, chuns for the Overworld, players, etc. This command will help prevent crashes and lags.

Step #2: Access Your Server's File Manager

To access your file manager, you have to press the WIN+R key, then type in% APPDATA% followed by the OK button. If you follow this process well, the AppData folder will open; scroll down to locate a folder with .minecraft. This will contain your server details.

Step #3: Delete Json Files

After reviewing your server docs, find out if a file is missing or invalid. Then, delete the invalid .json files and replace them with the corrected ones. This will fix the tick loop error issue, and prevent it from happening again.
