Reading the Logs

Reading your server logs is one of the most effective ways to diagnose problems. Log lines contain timestamps and severity levels that help you pinpoint issues.

Access your server logs

You can read the current logs of a running server directly in the Console tab.

Console tab

To read past logs, open Server Files and look for a folder named logs or files like latest.log or debug.log. In some cases you may find crash report files (for example, crash-2026-02-13_10.00.00-server.txt).

Reading the logs

Log lines start with the time and the log level:

[13:50:55] [Server thread/INFO]: Starting minecraft server version 1.21.4

To identify problems, look for lines with the ERROR level:

[10:56:03] [Server thread/ERROR]: Encountered an unexpected exception

The surrounding lines of an error often provide further information. If you do not understand the error message, search for the exact text online to see if other servers have had similar issues.
