What Is Exception in server tick loop?

The “exception in server tick loop” is a common error message that can occur in Minecraft servers. This error message can be caused by a variety of different issues, but one of the most common causes is problems with some .json files that are used by the server.

The specific files that are often associated with this error message are ops.json, usercache.json, and whitelist.json. These files are used by the server to manage player permissions and access. If there is a problem with any of these files, it can cause the server to crash and display the “Exception in server tick loop” error message.

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 command will help prevent crashes and lags.

Step #3: Delete Json Files

To delete these files, navigate to your server directory and locate the files in the appropriate folder (e.g. “world” folder for ops.json). Once you have located the files, delete them from the folder.

Step #4: Start Your Server

After you have completed the previous troubleshooting steps, it’s time to start up your Minecraft server again. To do this, simply navigate to the server directory and run the server executable file.
